Parentheses -2 to the 3rd power times 4 to the 4th power times 3 to the second power / -2 * 4 * 3 to the 3rd power

216/7

Step-by-step explanation:

196=2(x−1)x−12

2

Multiply both sides by 2(x-1)2(x−1).

\frac{6}{19}\times 2(x-1)=x-12196×2(x−1)=x−12

3

Use this rule: \frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}ba×dc=bdac.

\frac{6\times 2(x-1)}{19}=x-12196×2(x−1)=x−12

4

Simplify  6\times 2(x-1)6×2(x−1)  to  12(x-1)12(x−1).

\frac{12(x-1)}{19}=x-121912(x−1)=x−12

5

Multiply both sides by 1919.

12(x-1)=19x-22812(x−1)=19x−228

6

Expand.

12x-12=19x-22812x−12=19x−228

7

Subtract 12x12x from both sides.

-12=19x-228-12x−12=19x−228−12x

8

Simplify  19x-228-12x19x−228−12x  to  7x-2287x−228.
