7x-3=39 7x=42 x=6
x2-7x-18 = (x-9)(x+2) when factored
7x + 6 = -18 7x = -24 x = -24/7 x = -3.428571 recurring (that is, -3.428571428571...)
v/7x = w/y Multiply both sides of the equation by x, to get: v/7 = xw/y Multiply both sides of this equation by y/w, to get: vy/7w = x .

Assume you mean -7x-2=0 solve for x -7x-2=0 -7x=2 -x=2/7 X=-2/7
x2+7x x(x+7)
7x-3=39 7x=42 x=6
y = -7x 0 = -7x 0 = x x-intercept point is (0, 0).
7x+17 = 45 7x = 45-17 7x = 28 x = 4
