-7 +2x = x + 8 2x - x = 7 + 8 x = 15
X=7
3x-5
f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
The answer is (3.5)2 plus (4)2 equals 410.
6x - 8 + 2x - 5 = 7 - 2x ?
X=7
It is 2x - 8
It is 2x - 8
3x-5
x=2
2x + 8 + x = 2x + 15 simplify 2x to both sides since they have the same sign8 + x = 15 subtract 8 to both sidesx = 7
f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
