Question

Solve the equation 3(1+7) -x =-137

Answer 1

3(1+7)-x=-137

(3+21)• -x =-137

-24x=-137

x=137

24

x=34.25

Answer 2

Answer:

113

Step-by-step explanation:

Step 1: Find the brackets.

1+7=8

Step 2:

3x8-x=-137

find 3x8

3x8=24

step 4:

24-x=-137

work x backwards to find the value of x.

WHAT HAPPENED TO X?

x was subracted from 24. REVERSE would be to add 24.

24-x+24. the 24's cross each oher out.

step 5:

- what you do to one side YOU MUST do to the other.

-137+24=-113

step 6

-x=-113

multiply both sides by -1 to make x positive.

you end up with: 113
