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

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 11 :

$- x = - 10x + 22 + 11$

$- x = - 10x + 33$

Subtract the sides of the equation plus 10x

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

$9x = 33$

Divided the sides of the equation by 9 

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

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

And we're done.

Thanks for watching buddy good luck.
