8x - 4 = -7 + 5x8x - 5x - 4 = -7 + 5x - 5x subtract 5x from both sides3x - 4 + 4 = -7 + 4 add 4 to both sides3x = -3x = -3/3 = -1
5x + 4 - 8x = 13 5x + 4 + -8x = 13 (Put the x variables together) 5x + -8x = -3x -3x + 4 = 13 | -4 | -4 (Subtract 4 from both sides) -3x = 9 (Divide both sides by -3 to get the 'x' by itself) ---- --- -3 -3 x = -3
6x+1-x-3 = 8x-5-8 5x-2 = 8x-13 5x-8x = -13+2 -3x = -11 x = 11/3
3x + 11 + 5x = 75 Collect 'like terms on the LHS 8x + 11 = 75 Subtract '11' from both sides 8x = 64 Divide both sides by '8' 8x/8 = 64/8 x = 8
8x - 3 = 5x + 1Add 3 to each side:8x = 5x + 4Subtract 5x from each side:3x = 4Divide each side by 3:x = 4/3
8x-4 = -7+5x 8x-5x = -7+4 3x = -3 x = -1
3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)
