Question

x = 0.8x + 72

Answer 1

solve for x

Answer 2

Right solve for 'x' ...what would we do? we have 2 'x' terms...and we want 1 'x' term.....so we combine them

subtract .8x from both sides

x - .8x = 72

what is x - .8x?

Answer 3

so its .2x=72
72/.2=360

Answer 4

That would be correct!

now check it

x = .8x + 72
360 = .8(360) + 72
360 = 288 + 72
360 = 360

So yes it is correct
x = 360
