Question

Sara made an error in solve the one-step equation below.5x + 9 = 29-9 -9- 4x = 29/4. /4x = -7.25What is the error that Sara made?What should Sara had done to solve the one-step equation above insteadof what she did?What is the answer that Sara should have found for the above one-step equation?*

Answer 1

$5x+9=29$

To solve this one-step equation you:

1. Substract 9 in both sides of the equation:

In this step is the mistake as Sara gets as result -4x=29 and the corret result of substract 9 in both sides of the equation is 5x=20.

2. Divide both sides of the equation into 5:

Then, the answer that Sara should found for the equation is x=4
