Solve for X 4X-(9-3X)=8X-1

Nataliya [291]

4x - (9 - 3x) = 8x - 1

4x - (9) - -(3x) = 8x - 1

4x - 9 + 3x = 8x - 1

7x - 9 = 8x - 1 (-8x from each side)

-x - 9 = -1 (+9 to each)

-x = 8 (divide -1 from each side)

x = -8

Answer: $\frac{2x(5x + 1)}{4x - 1}$

Step-by-step explanation:

$\frac{4x^{3}-12x^{2}}{4x^{2}+7x - 2}$ ÷ $\frac{2x^{2}-6x}{5x^{2}+11x + 2}$

= $\frac{4x^{2}(x - 3)}{(4x - 1)(x + 2)}$ ÷ $\frac{2x(x - 3)}{(5x + 1)(x + 2)}$

= $\frac{4x^{2}(x - 3)}{(4x - 1)(x + 2)}$ x $\frac{(5x + 1)(x + 2)}{2x(x - 3)}$

= $\frac{2x(5x + 1)}{4x - 1}$
