(x + 3)(x + 4) = x2 + 7x + 12
x/3x + 4 = 4 1/3.
It is: (-4)^2 +(-4) -9 = 3 when x is equal to -4
-7
X 3 plus x-142 plus x is an equation equal to x3+2x-142.
x < /= -4
if you mean x + 4 = 7 then x = 3
In 6x + 4 = 12, x = 4/3
No it equals 6 because x and y equal 1 in themselves
The answer is x = -16/3
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
It is 123.99
