"Solve 4r -7 = 8r + 13"

Start with the given equation

Subtract 8r from both sides

Add 7 to both sides

Combine like terms 4r and -8r on the left side to get -4r

Combine like terms on the right side

Divide both sides by -4 to isolate r

Reduce

Answer:
So our answer is

"Solve 5x - 8 = 6 - 2x"

Start with the given equation

Add 8 to both sides

Add 2x to both sides

Combine like terms 5x and 2x on the left side to get 7x

Combine like terms on the right side

Divide both sides by 7 to isolate x

Reduce

--------------------------------------------------------------
Answer:
So our answer is

"Solve t/5 - 7 + 31 = 8(6-4)"

Simplify the right side

Multiply both sides by 5

Distribute and multiply

Start with the given equation

Add 35 to both sides

Subtract 155 from both sides

Combine like terms on the right side

--------------------------------------------------------------
Answer:
So our answer is

"Solve 9-5(4-3) = -16 x/3"

Distribute and simplify the left side

Multiply both sides by 3

Divide both sides by -16

Divide both sides by -16
