Solve the system of equations by the addition method <br> { 5x-y=-3<br> { 4x+3y=-48

Svetach [21]

Answer:

(-3,-12)

Step-by-step explanation:

Multiply the first equation by three to match the second equations y-term

3(5x-y=-3)
4x+3y=-48

15x-3y=-9
4x+3y=-48

The y-terms cancel out

15x=-9
4x=-48

Add the x-terms with each other and the terms after the equal sign as well

19x=-57

Divide -57 by 19

x=-3

Input your x-term (-3) into one of the two first equations and multiply

Either:

5(-3)-y=-3 or

4(-3)+3y=-48

-15-y=-3 or

-12+3y=-48

Simplify your terms

-y=12

3y=-36

Divide

y=-12

y=-12
