Solve -11 - x + = - 5 (2x-3) + 7
garri49 [273]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

- 11 - x =  - 5(2x - 3) + 7

- 11 - x =  - 10x + 15 + 7

- 11 - x =  - 10x + 22

Subtract the sides of the equation plus<em> </em><em>1</em><em>1</em> :

- x =  - 10x + 22 + 11

- x =  - 10x + 33

Subtract the sides of the equation plus <em>1</em><em>0</em><em>x</em>

10x - x = 10x - 10x + 33

9x = 33

Divided the sides of the equation by <em>9</em><em> </em>

\frac{9}{9}x =  \frac{33}{9} \\

x =  \frac{33}{9} =  \frac{3 \times 11}{3 \times 3} =  \frac{11}{3} \\

And we're done.

Thanks for watching buddy good luck.
