Question

10×+2=7 what is equal to 2x?

Answer 1

$x in (-oo:+oo) 2/7 = 2*x // - 2*x 2/7-(2*x) = 0 2/7-2*x = 0 2/7-2*x = 0 // - 2/7 -2*x = -2/7 // : -2 x = -2/7/(-2) x = 1/7 x = 1/7$

Answer 2

2X=1 because you subtract 2 from each side to isolate x, and then you get 10x=5. Then divide 5 by 10, which leaves you with x=1/2, so you multiply that by 2 to solve for 2X, which is 1
