8x = 5x+24 8x-5x = 24 3x = 24 x = 8
Add the equations: 8x - y = 8 ie 8x - 8 = y so 5x - 5(8x - 8) = -30 which is 5x - 40x + 40 = -30 ie -35x = -70 making x = 2 and y = 8.
6x+1-x-3 = 8x-5-8 5x-2 = 8x-13 5x-8x = -13+2 -3x = -11 x = 11/3
5x-13x+6=0 5x-13x=-6 -8x=-6 -8x/-8=-6/-8 x = 3/4
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
5x-3=2-8x 5x-3+3=2-8x+3 5x=5-8x 5x+8x=5-8x+8x 13x=5 x=5/13
8x = 5x+24 8x-5x = 24 3x = 24 x = 8
Add the equations: 8x - y = 8 ie 8x - 8 = y so 5x - 5(8x - 8) = -30 which is 5x - 40x + 40 = -30 ie -35x = -70 making x = 2 and y = 8.
6x+1-x-3 = 8x-5-8 5x-2 = 8x-13 5x-8x = -13+2 -3x = -11 x = 11/3
3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)
5x-13x+6=0 5x-13x=-6 -8x=-6 -8x/-8=-6/-8 x = 3/4
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
5x + 5 = 8 -3x 5x = 3 -3x 8x = 3 x = 0.375
6x - 3x = 5x - 10x + 12 6x - 3x - 5x + 10x = 12 8x = 12 8x/8 = 12/8 x = 12/8 = 3/2 x = 1.5
5x2=8x Divide with x on both sides5x= 8 Solve xx=8/5
3x^2 + 5x - 8 = 0 + 8 + 8 3x^2 + 5x = 0 8x ^2 = 0
32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3
