10 -3x+8x = 25 -3x+8x = 25-10 5x = 15 x = 3
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
X equals 9.
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
x = 3
8x - 23= 3x + 2 +23 +23 8x=3x + 25 -3x -3x 5x=25 x=5 the answer is X=5
10 -3x+8x = 25 -3x+8x = 25-10 5x = 15 x = 3
-2
3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
X equals 9.
3x-3x+4x^2+8x=4x^2+8x
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2
X = 1
x = 3
11x = 8x-6.............. 11x-8x = -6................... 3x= -6 x = -2
