The value of x is 2
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
X=5/12
subtracting gives 4x = -12 so x = -3
8x + 9.16 = 4x + 16 8x - 4x = 16 - 9.16 4x = 6.84 x= 1.71
8x+5=4x+17 4x=12 subtract 4x from right and 5 from left x=3 divide both sides by 4
x = -8, y = 10
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
8x + 10 = 3x +145x = 4x = 4/5 = 0.8Improved answer:8x+10 = 4x+148x-4x = 14-104x = 4x = 1
8x-1 = -4x+23 8x+4x = 23+1 12x = 24 x = 2
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
8x+2y=4x=-y/4+0.5y=-4x+2
