Solve by Graphing 12x-4y=24 , 3x=y+6

$12 x - 4 y = 24$ , $3 x = y + 6$

Step 1

Subtract $12 x$ from both sides of the equation.

$- 4 y = 24 - 12 x$

$3 x = y + 6$

Step 2

Divide each term in $- 4 y = 24 - 12 x$ by $- 4$ and simplify.

Divide each term in $- 4 y = 24 - 12 x$ by $- 4$ .

$\frac{- 4 y}{- 4} = \frac{24}{- 4} + \frac{- 12 x}{- 4}$

$3 x = y + 6$

Simplify the left side.

Cancel the common factor of $- 4$ .

Cancel the common factor.

$\frac{- 4 y}{- 4} = \frac{24}{- 4} + \frac{- 12 x}{- 4}$

$3 x = y + 6$

Divide $y$ by $1$ .

$y = \frac{24}{- 4} + \frac{- 12 x}{- 4}$

$3 x = y + 6$

$y = \frac{24}{- 4} + \frac{- 12 x}{- 4}$

$3 x = y + 6$

$y = \frac{24}{- 4} + \frac{- 12 x}{- 4}$

$3 x = y + 6$

Simplify the right side.

Simplify each term.

Divide $24$ by $- 4$ .

$y = - 6 + \frac{- 12 x}{- 4}$

$3 x = y + 6$

Cancel the common factor of $- 12$ and $- 4$ .

Factor $- 4$ out of $- 12 x$ .

$y = - 6 + \frac{- 4 (3 x)}{- 4}$

$3 x = y + 6$

Cancel the common factors.

Factor $- 4$ out of $- 4$ .

$y = - 6 + \frac{- 4 (3 x)}{- 4 \cdot 1}$

$3 x = y + 6$

Cancel the common factor.

$y = - 6 + \frac{- 4 (3 x)}{- 4 \cdot 1}$

$3 x = y + 6$

Rewrite the expression.

$y = - 6 + \frac{3 x}{1}$

$3 x = y + 6$

Divide $3 x$ by $1$ .

$y = - 6 + 3 x$

$3 x = y + 6$

$y = - 6 + 3 x$

$3 x = y + 6$

$y = - 6 + 3 x$

$3 x = y + 6$

$y = - 6 + 3 x$

$3 x = y + 6$

$y = - 6 + 3 x$

$3 x = y + 6$

$y = - 6 + 3 x$

$3 x = y + 6$

Step 3

Rewrite the equation as $y + 6 = 3 x$ .

$y + 6 = 3 x$

$y = - 6 + 3 x$

Step 4

Subtract $6$ from both sides of the equation.

$y = 3 x - 6$

$y = - 6 + 3 x$

Step 5

Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution.

Always true
