-4x=7y-28 -4x+28=7y -4x/7+4=y A line with a y-int of 4 and a slope of -4/7
8x-5=23+4x 8x-5-4x=23+4x-4x 4x-5=23 4x-5+5=23+5 4x=28 4x/4=28/4 x=7
x-intercept of y equals -4x plus 4 y = -4x + 4 0 = -4x + 4 -4 = -4x 1 = x So 1 is the x-intercept
4x + 6 = 34 Subtract 6 from both sides: 4x = 28 Divide both sides by 4: x = 7
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?
