Solve the system of equations by adding. checking your answer

Mathematics
1 answer:
Brut [27]3 years ago
3 0

Answer:

Step-by-step explanation:

This is very easy, because the coefficients of the y terms are 2 and -2. You can easily eliminate the y terms by adding the equations together:

2x + 2y = 2

3x - 2y = 43

-----------------

5x + 0y = 45,  so x = 9

Use the value of x to solve for  y:

2(9) + 2y = 2

y = -8

(x,y) = (2, -8)
