PLEASE HELP WILL MARK BRAINLIEST TO FIRST CORRECT RESPONSE What is the first step in solving the equation 4.2y - 5.2 = 18.5 ?

Respuesta :

mathmate
4.2y - 5.2 = 18.5
Step 1: add 5.2 to both sides
4.2y-5.2+5.2 = 18.5+5.2 => 4.2y = 23.7
Step 2: divide both sides by 4.2
4.2y/4.2=23.7/4.2 => y=23.7/4.2 = 5.643 (to nearest 1/1000th)
first you move - 5.2 for + 5.2

4.2y = 18.5 + 5.2

4.2y = 23.7

divide 4.2

y = 5.6
