PLS help<br> solve for x: -6(2x-5) = 18

Mashutka [201]

Hey!

$-6(2x-5) = 18$

Switch it around and it becomes:

$2x - 5 = 18 \div -6$

First find 18 ÷ -6

$18 \div -6 = -3$

Positive ÷ negative OR negative ÷ positive is always negative.

That leaves you with:

$2x - 5 = -3$

Switch that around and it becomes:

$-3 + 5 = 2x$

Find -3 + 5

$-3 + 5 = 2$

That leaves you with:

$2 = 2x$

Divide both sides by 2 to leave <em>x</em> alone

$\frac{2}{2} = \frac{2x}{2}$

$\framebox{x = 1}$
