8x - 4x + 7 = 94x + 7 = 94x = 9-74x = 2x = 4/2x = 1/2x = 0.5
It is an algebraic expression involving x. Of do you mean 'what is x if 2x - 9 equals 9?' 2x - 9 = 9 ⇒ 2x - 9 + 9 = 9 + 9 ⇒ 2x = 18 ⇒ 2x ÷ 2 = 18 ÷ 2 ⇒ x = 9
2x-3=9 so 2x=12 and x=6
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
2x-3=4x+9 -2x-12=0 2x=-12 x=-6
