Solve for x 3x+y=z

$3 x + y = z$

Step 1

Subtract $y$ from both sides of the equation.

$3 x = z - y$

Step 2

Divide each term in $3 x = z - y$ by $3$ and simplify.

Divide each term in $3 x = z - y$ by $3$ .

$\frac{3 x}{3} = \frac{z}{3} + \frac{- y}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 x}{3} = \frac{z}{3} + \frac{- y}{3}$

Divide $x$ by $1$ .

$x = \frac{z}{3} + \frac{- y}{3}$

Simplify the right side.

Move the negative in front of the fraction.

$x = \frac{z}{3} - \frac{y}{3}$
