Question

Kelly solved an equation: H/ 4 - 11 = 13 using two inverse operations of adding 11 to both sides of the equations, and then dividing both sides by 4. Her answer is H = 6. What is her error?

Answer 1

She should have multiplied by 4, not divided

Explanation:

Given

`(H)/(4)` - 11 = 13 ( add 11 to both sides ) ← correct

`(H)/(4)` = 24 ( multiply both sides by 4 to clear the fraction )

H = 4 × 24 = 96

H is divided by 4, thus the inverse operation is to multiply
