In the equation 3x plus 7 equals 13, x is equal to 2.
y = (13 - 3x)/2 and that cannot be simplified further.
(2, 7)
3x + 2y = 13Subtract 3x from each side:2y = -3x + 13Divide each side by 2:y = (-3/2)x + (13/2)The graph is a straight line, with a slope of (-3/2),through the point (0, 13/2) .
3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13
