Can someone help me solve this one?

t itxoy ot ot oy oy o y oy oy

x=−7  and y=−1

Step-by-step explanation:

3x−9y=−12,3x−15y=−6

Choose one of the equations and solve it for x

3x−9y=−12

Add 9y to both sides of the equation.

3x=9y−12

Divide both sides by 3.

x=  1/3  (9y−12)

Multiply  

1/3 times 9y−12.

x=3y−4

Substitute 3y−4 for x in the other equation, 3x−15y=−6.

3(3y−4)−15y=−6

Multiply 3 times 3y−4.

9y−12−15y=−6

Add 9y to −15y.

−6y−12=−6

Add 12 to both sides of the equation.

−6y=6

Divide both sides by −6.

y=−1

Substitute −1 for y in x=3y−4. Because the resulting equation contains only one variable, you can solve for x directly.

x=3(−1)−4

Multiply 3 times −1.

x=−3−4

Add −4 to −3.

x=−7
