5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
That factors to (x - 2)(x + 7)
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
It is: 12x
x = 6, y = -4
x=6Solution:x + 2x + 14 = 5x + 214 - 2 = 5x - 3x12 = 2xx = 12/2 = 6
x+2x+14=5x+214-2=5x+2x+x10=8x10/8=xx=5/4 ans.
(x - 7)(x + 2)
0. 6x + 3 = 5x + 141. 6x = 5x + 11 [subtracting 3]2. x = 11 [subtracting 5x]
5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
5x + 14 = 95 - 4x 5x + 4x = 95 - 14 9x = 81 x = 81/9 x = 9

5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
7 x 4 = 2828 - 14 = 14Therefore 5x = 1414/5 = 2.8Therefore x = 2.8
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
5x plus 3 does equal 3 plus 5x; commutative law.
