Question

13 – 6x = 2(8 + 3x) x= ???????

Answer 1

Answer:

$13-6x=2\left(8+3x\right)$

$13-6x=16+6x$

$13-6x-13=16+6x-13$

$-6x=6x+3$

$-6x-6x=6x+3-6x$

$-12x=3$

$\frac{-12x}{-12}=\frac{3}{-12}$

$x=-\frac{1}{4}$

or

$x=-0.25$

Answer 2

Answer:

-1/4 = x

Step-by-step explanation:

first, we distribute the 2 into the parenthesis

13 - 6x = 2(8 + 3x)

13 - 6x = 16 + 6x

then, we add 6x to both sides to move all of the x terms onto one side

13 - 6x = 16 + 6x

13 = 16 + 12x

next, we subtract 16 on both sides

13 = 16 + 12x

-3 = 12x

next, we divide both sides by 12 to isolate x

-3 = 12x

-3/12 = x

finally, we simplify the fraction

-3/12 = x

-1/4 = x
