9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
-(x - 9)(x + 2)
18+18+18+19+23+23+24+24=167
x = 22/7
It is an equation and the value of x is 2
7x + 6 = -18 7x = -24 x = -24/7 x = -3.428571 recurring (that is, -3.428571428571...)
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
7x+6 = -3x-24 7x+3x = -24-6 10x = -30 x = -3
(x2 + 7x - 18) = (x + 9)(x - 2)
x^2 + 7x -18 = (x - 2)(x + 9)
To simplify the expression 18 + 7x - 12 + 5x, you first combine like terms. Combine the constants (18 and -12) to get 6. Then, combine the x terms (7x and 5x) to get 12x. Therefore, the simplified expression is 6 + 12x.
6x+x=7x
x2+7x-18 = (x+9)(x-2) when factored
-(x - 9)(x + 2)
18+18+18+19+23+23+24+24=167
x = 22/7
