Question

What is the value of m in the equation 5m − 7 = 6m + 11? ((99) points!! Give me you number? Maybe?)

1) 18
2) 1
3) −18
4) −1

Answer 1

$5m-7=6m+11$

We want to isolate "m" on one side of the equation and have a number on the other side. Let's start by subtracting both sides by 5m

$5m-7-5m=6m+11-5m$

$-7=m+11$

Now, let's subtract both sides by 11

$-7-11=m+11-11$

$-18=m$

We now have the value of m.

The next thing I'm going to do is a bit tedious, but you typically want to have the variable on the left side of the equation in the field of math. It's a good habit to develop now.

$m=-18$

Thus, the answer is choice 3, -18. Let me know if you need any clarifications, thanks!

Answer 2

Answer:

3.

Step-by-step explanation:

5m-6m=11+8

-m=18

multiply with negative sign throughout, and you get

m= -18
