Answer:

x=3

y = 2

Solution is (3,2)

Step-by-step explanation:

x + 2y = 7

x - 2y = -1

Solve the system of equations by elimination method

LEts add both equations

x + 2y = 7

x - 2y = -1

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

2x +0 = 6

2x = 6

Divide both sides by 2

x= 3

Now plug in x=3 in first equation

x + 2y = 7

3 + 2y = 7

subtract 3 from both sides

2y = 4

divide both sides by 24

y = 2

Solution is (3,2)
