x=5
Add 4x - 2 to each side: 5x = 5 x = 1
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
4x24=96 20 x 4 = 80 4 x 4 = 16 80 + 16 = 96
4x = 24 x = 24 ÷ 4 x = 6
-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
8x-1=23-4x 12x=24 x=2
x = 5
-2x=-4x*24 x=12
x=5
x= -.5
2x/3 = 8 + 4x2x = 24 + 12x-24 = 10x-2.4 = x
Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.
X and Y could equal any number of things. For instance, if x=6 and y=0, then that will equal 24. Or if x=8 and y=2, then that will equal 24.
4x = 16Divide each side of the equation by 4:x = 4
If you're trying to find x: 8x-1=-4x+23 8x+4x=23+1 12x=24 x=24/12 x=2 wasn't really sure if that's what your question was but hope it helped =)
