Erica solved the equation βˆ’5x βˆ’ 25 = 78; her work is shown below. identify the error and where it was made. (5 points)

βˆ’5x βˆ’ 25 = 78

step 1: βˆ’5x βˆ’ 25 βˆ’ 25 = 78 βˆ’ 25

step 2: βˆ’5x = 53

step 3: =

step 4: x =

step 1: she should have added 25 to each side.

step 1: she should have divided both sides by βˆ’5.

step 3: she should have divided both sides by βˆ’5.

step 3: she should have multiplied both sides by βˆ’5
