2y = 4 (divide both sides by 2 to solve) y = 2
(2,-2)
7
y=5
Are you sure the directions don't have "solve the equation as x=___ and y=___"
2y = 4 (divide both sides by 2 to solve) y = 2
(2,-2)
y + y + 2 = 182y + 2 = 182y = 16y = 8whew !
7
y=5
This cannot be solved. It needs 2 equations to solve for 2 unknowns.
Are you sure the directions don't have "solve the equation as x=___ and y=___"
You can't. You need 2 equations to solve for 2 unknowns
y=4
First, solve for y.y=-8xif x=2, then y=-16.
2y = 15 y = 15/2 y = 7.5
subtract 2 from both sides 2 and 5 then youll get the answer
