$\frac{3 x \cdot 2 + x}{2} + \frac{17 \cdot 2}{2} + \frac{- 5 \cdot 2}{2} = 180$

Combine the numerators over the common denominator.

$\frac{3 x \cdot 2 + x + 17 \cdot 2 - 5 \cdot 2}{2} = 180$

Simplify each term.

Multiply $2$ by $3$ .

$\frac{6 x + x + 17 \cdot 2 - 5 \cdot 2}{2} = 180$

Multiply $17$ by $2$ .

$\frac{6 x + x + 34 - 5 \cdot 2}{2} = 180$

Multiply $- 5$ by $2$ .

$\frac{6 x + x + 34 - 10}{2} = 180$

Simplify by adding terms.

Add $6 x$ and $x$ .

$\frac{7 x + 34 - 10}{2} = 180$

Subtract $10$ from $34$ .

$\frac{7 x + 24}{2} = 180$

Step 2

Multiply both sides by $2$ .

$\frac{7 x + 24}{2} \cdot 2 = 180 \cdot 2$

Step 3

Simplify.

Rewrite the expression.

$7 x + 24 = 180 \cdot 2$

Simplify the right side.

Multiply $180$ by $2$ .

$7 x + 24 = 360$

Step 4

Solve for $x$ .

Move all terms not containing $x$ to the right side of the equation.

Subtract $24$ from both sides of the equation.

$7 x = 360 - 24$

Subtract $24$ from $360$ .

$7 x = 336$

Divide each term in $7 x = 336$ by $7$ and simplify.
