Question

7th grade math asap

1: -126=14k
2: -7+m=8
3: -17=x -15
4: -5=a/18

Answer 1

1. k = -9

2. m = 15

3. x = -2

4. a = -90

Explanation:

When doing these problems set them up as if the equal sign is a dividing line between two sides.

1. -126=14k

Divide both sides by 14 to get rid of the coefficient.

This gives you your answer -9=k

2. -7+m=8

Add 7 to both sides to isolate the variable.

This gives you your answer m=15

3. -17=x-15

Add 15 to both sides to isolate the variable.

This gives you your answer x=-2

4. -5=a/18

Multiply both sides by 18 to get rid of the denominator.

This gives you your answer of a=-90

Hope this helped!
