Answer:
y = -47
Step-by-step explanation:
To find the midpoint of two points, add them together and divide by 2
(y+33)/2 = -7
To find y, multiply each side by 2
(y+33)/2 *2 = -7*2
y+33 = -14
Subtract 33 from each side
y+33-33 = -14-33
y = -47
To solve for x and y, isolate each variable and simplify your equation:
Solve for x:
2x+7=3y-1 (Subtract 7 on each side)
2x=3y-8 (Divide by 2 on each side)
x=

Solve for y:
2x+7=3y-1
2x+8=3y (Add 1 on each side)

=y (Divide by 3)
y=
