Answer 1

Hello there!

The answer it should be the the last option "x=8".

$-5x+6(4x+15)=242$

Explanation:

First you had to expand the form.

$6(4x+15):24x+90$

$-5x+24x+90=242$

Then you had to add similar by the elements.

$-5x+24x=19x$

$19x+90=242$

You had to subtract by 90 from both sides of the equation.

$19x+90-90=242-90$

Simplify

$19x=152$

Divide by 19 from both sides of the equation.

$\frac{19x}{19}=\frac{152}{19}$

Simplify it should be the correct answer.

$x=8$
