Question

Which process was used to obtain the equation shown in Step 2?
Step1: x/4-1/5=2
Step2: 5x-4=40
added 38 to both sides of the equation
divided both sides of the equation by 20
multiplied both sides of the equation by 20
added 1/5 to both sides of the equation

Answer 1

to equal the step 2, we would have to determine that 20 was our new denominator and multiply the first fraction by 5, the second by 4 and the 2 by 20.

multiplied by sides of the equation by 20
