If: 4x-4 = 12
Then: x = 4
-4x-4 equals -16. Add 4 to both sides; -4x equals -12. Divide both sides by -4; x equals 3.
If: 4x-4 = 12 Then: x = 4
x-intercept of y equals -4x plus 4 y = -4x + 4 0 = -4x + 4 -4 = -4x 1 = x So 1 is the x-intercept
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
4x = 16Divide each side of the equation by 4:x = 4
4x - 9 = 35 4x = 35 + 9 4x = 44 4x/4 = 44/4 x=11
5x + (4 - 4x) = 05x + 4 - 4x = 0x + 4 = 0Subtract 4 from each side:x = -4
Parallel. They both have a slope of 4.
Right but wrong. It equals -4x
Only if 4 dollars plus 4 dollars equals 8 dollars.And if you had another 4x, you'd have a dozen-x.
