Answer:
w = ( -7 +3y) ÷ 5
Step-by-step explanation:
5w -3y +7 =0
5w - 3y = -7 ( after subtracting 7 from both sides )
5w = -7 + 3y (after adding 3y on both sides.)
5w ÷ 5 = (-7 + 3y ) ÷ 5 ( divide 5 on both sides)
w = (-7 + 3y ) ÷ 5 after dividing 5 on both sides)

but it would be better if you search up a video on youtube or somewhere, so you can understand more easily. I've just explained it briefly.
