x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
4-2x-9 = -19 -2x = -19-4+9 -2x = -14 x = 7
2x - 6 = x + 5 Isolate x. 2x - x = 6 + 5 x = 11
x=-7
2x-3 = 11 2x = 11+3 2x = 14 x = 7
x + 2x + 5 = x +19 3x + 5 = x +19 3x - x = 19 - 5 2x = 14 x = 7
4-2x-9 = -19 -2x = -19-4+9 -2x = -14 x = 7
If 2x + 5 = 11, then 11 - 5 = 2x 6 = 2x 3 = x
x equals 19
2x - 6 = x + 5 Isolate x. 2x - x = 6 + 5 x = 11
x=-7
x + 2y = 27 2x - y = 19 y = 2x - 19 x + 2(2x - 19) = 27 x + 4x - 38 = 27 5x = 65 x = 13 y = 2(13) - 19 y = 7
2x-3 = 11 2x = 11+3 2x = 14 x = 7
2x-11=10 then 2x=21 so x =21/2
2x+3 = -11 2x = -11-3 2x = -14 x = -7
2x - 7 = 15 2x = 22 x = 11
2x - 5 = 11 2x = 11 + 5 2x = 16 2x /2 = 16 /2 x = 8
