Solve for r 6r-4+94=180

$6 r - 4 + 94 = 180$

Step 1

Add $- 4$ and $94$ .

$6 r + 90 = 180$

Step 2

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

Subtract $90$ from both sides of the equation.

$6 r = 180 - 90$

Subtract $90$ from $180$ .

$6 r = 90$

Step 3

Divide each term in $6 r = 90$ by $6$ and simplify.

Divide each term in $6 r = 90$ by $6$ .

$\frac{6 r}{6} = \frac{90}{6}$

Simplify the left side.

Cancel the common factor of $6$ .

Cancel the common factor.

$\frac{6 r}{6} = \frac{90}{6}$

Divide $r$ by $1$ .

$r = \frac{90}{6}$

Simplify the right side.

Divide $90$ by $6$ .

$r = 15$
