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?

She should have multiplied by 4, not divided

Step-by-step explanation:

Given

- 11 = 13 ( add 11 to both sides ) ← correct

= 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

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

no solution

step-by-step explanation:

there is not enough information in the problem to solve.
