It is the same as 8x+2 when simplified
8x - 23= 3x + 2 +23 +23 8x=3x + 25 -3x -3x 5x=25 x=5 the answer is X=5
3x-3x+4x^2+8x=4x^2+8x
-2
11x = 8x-6.............. 11x-8x = -6................... 3x= -6 x = -2
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
(3x + 2)(x + 2) so x = -2/3 or -2
7. 8x-40=2x+2 4x-20=1x+1 3x-21=0 3x=21 therefore x=7
6-3x = 5x-10x+2 4 = 8x-10x 4 = -2x x = -2
Add the coefficients of the variable term X. 2 + 3 + 8 = 13X
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
