4x =20x=20/4x=5
y = 4x-3
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
2y = 4x + 4y = 2x + 2
8x + 10 = 3x +145x = 4x = 4/5 = 0.8Improved answer:8x+10 = 4x+148x-4x = 14-104x = 4x = 1
(6, 0) and (0, 8)
x=3 y=2 z=6
4x + 3y = 6y 4x = 3y 4/3 x = y The slope is 4/3 and the y intercept is 0.
None because the discriminant of this quadratic equation is less than zero.
-4x + y = 8At the x-intercept, 'y' is zero.-4x = 8-x = 2x = -2At the y-intercept, 'x' is zero.y = 8

y intercept: x = 0 3y = 0 y = 0 x intercept: y=0 -4x = 0 x = 0 (0,0)
4x-14
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
4x plus 7 plus 3x equals 19 plus xx = 2
