Answer:

x=6

Step-by-step explanation:

2(x-4)+x=10

expand into 3x-8

add 8 to both sides 3x-8+8=10+8

simplify 3x=18

divide both sides by 3 3x/3=18/3

simplify x=6

Answer:

d. x = 1 1/3

Step-by-step explanation:

Step 1: Add 5/6x to both sides.

$\frac{2}{3}x + \frac{5}{6}x = 2 - \frac{5}{6}x + \frac{5}{6}x$
$\frac{3}{2}x = 2$

Step 2: Multiply both sides by 2/3.

$\frac{3}{2}x * \frac{2}{3} = 2 * \frac{2}{3}$
$x = \frac{4}{3}$
$x = 1 \frac{1}{3}$
