Simplify 42 Solve this Equation
Make simpler and solve this equation: 4m + 9 + 5m – 12 = 42.
Solution:
Given, the equation is:4m + 9 + 5m – 12 = 42
We have to simplify the equation.
On rearranging
4m + 5m – 3 = 42
By grouping,
m(4 + 5) = 42 + 3
9m = 45
m = 45/9
m = 5
Therefore, the value of m is 5.
Example:
Simplify and solve this equation: 5m + 6 + 3m + 12 = 42.
Solution:
Given, the equation is 5m + 6 + 3m + 12 = 42
We have to simplify the equation.
On rearranging,
5m + 3m + 6 + 12 = 42
By grouping,
m(5 + 3) + = 42 – 12 – 6
8m = 30 – 6
8m = 2
m = 24/8
m = 3
Therefore, the value of m is 3.
Simplify and solve this equation: 4m + 9 + 5m – 12 = 42?
- m = 5
Also, A, 4m + 9 + 5m – 12 = 42
4m + 5m = 42 +12 – 9
9m = 45
9m/9 = 45/9
m = 5
- 4(5) +9 +5(5) -12 =42
20 +9+25-12=42
Also, The other problems work the same way. To find M, here is what you do:
(4m + 5M) +9-12=42
9m -3 = 42
Also, 42 +3 = 9m -3 +3
9m =45
m = 45/9
m=5
Also, Answer 6
4m+9-5m-12=42
Also, first, combine like terms(m)
9m+9-12=42
finish combining like terms(9-12)
9m-3=42
Also, change the sign to 3 and move it with 42
9m-3=42
+3 +3
Also, the threes cancel
then take the 9m and divide it by the 42
42/9
Which Gives You A Positive 5
Although, It’s been a while since I’ve done this type of question, but I believe its m =5
Also, 9m=45 (add 12 to 42 than subtract 9=45)
45 divided by 9 equals 5
I am starting to think you don’t pay any attention in class and are just there to get answers for your homework.
Also, The very basic is to group them
4M + 9 + 5M -12 = 42
Although, group all numbers with an unknown, like 4 M and 5 M, and all the numbers together.
9M + 9 -12 = 42
9M -3 = 42
Also, Now group numbers by moving them to the same side of the equal sign
9M = 42 + 3
9M = 45
M = 45/9
M = 5
Answer 7
Simplify like terms:
9m-3=42.
Also, cancel out the three:
9m=45
Divide.
45/9=?
4m +9+5m-12=42
Also, 4m+5m= 42+12-9
9m=45 => m=5
How old are you, btw??
4m + 9 + 5m – 12 = 42
Also, combine like items:
4m + 5m = 9m
9 – 12 = -3
And you’re left with
9m – 3 = 42
Although, Then you isolate the variable on one side of the equal sign
Also, 9m – 3 + 3 = 42 + 3 (What you do to one side, you must do to the other)
9m = 45
9m/9 = 45/9
m = 5
Solve All Like Terms First
4m+5m=9m
9-12=-3
They put them all together in an equation
Also, 9m-3=42 (bring -3 on the other side and change the sign making it 9m=42+3)
9m/9=42+3/9 (the nine on the left side of the equation cancels out)
m=5 (the answer is A)
Answer 6
4m+9-5m-12=42
Also, first, combine like terms(m)
9m+9-12=42
Also, finish combining like terms(9-12)
9m-3=42
Also, change the sign of 3 and move it with 42
9m-3=42
+3 +3
the threes cancel
then take the 9m and divide it by the 42
42/9
Also, which gives you a positive 5
4m+9+5m-12 = 42
i.e., 4m+5m-3 = 42 (adding -12 with 9)
9m-3 =42 (4m+5m=9m)
i.e., 45= 9m (taking 3 to R.H.S)
i.e., m =5 (45/9=5)
m = +5
4m +9+5m-12=42
Also, 4m+5m= 42+12-9
9m=45 => m=5
