Answer:
x = - 2 , y = 2
( - 2, 2)
Explanation:

first equation add 1/2 to both sides
second equation subtract 2x from both sides

Solve the first equation

subtract x/2 from both sides

substitute
for y in the other equation

add
to 2x

subtract 1 from both sides

divide both sides by

x = - 2
substitute the value of x into an equation

distribute
y = 1 + 1
y = 2
x = -2, y = 2
( - 2, 2)
