Solve for g 10g-7g-3=18

$10 g - 7 g - 3 = 18$

Step 1

Subtract $7 g$ from $10 g$ .

$3 g - 3 = 18$

Step 2

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

Add $3$ to both sides of the equation.

$3 g = 18 + 3$

Add $18$ and $3$ .

$3 g = 21$

Step 3

Divide each term in $3 g = 21$ by $3$ and simplify.

Divide each term in $3 g = 21$ by $3$ .

$\frac{3 g}{3} = \frac{21}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 g}{3} = \frac{21}{3}$

Divide $g$ by $1$ .

$g = \frac{21}{3}$

Simplify the right side.

Divide $21$ by $3$ .

$g = 7$
