Answer:
(1, -8)
y= -8
x= 1
Step-by-step explanation:
7x-3y= 31
7x+y= -1
solve the equation
7x-3y=31
7x= -1-y
substitute the value of 7x into an equation
-1-y-3y=31
subtract -y to -3y
-1-4y=31
add both sides by 1
-4y=32
divide both sides by -4
y= -8
substitute the value of y into an equation
7x= -1-(-8)
distribute
7x=7
divide both sides by 7
x=1
