Answer:
1. k = -9
2. m = 15
3. x = -2
4. a = -90
Step-by-step 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!
