x-intercept of y equals -4x plus 4 y = -4x + 4 0 = -4x + 4 -4 = -4x 1 = x So 1 is the x-intercept
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?
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
-8x + 4 = -4x; (-8+4)x = -4; x = 1.
