Solving for y simply means isolate y on one side of the equation and everything else on the other. If 2y=-x+1, then we need to divide both sides by 2.
We end up with y=-1/2x+1/2
X+2Y=-1
-X -X
2Y=-x-1
/2 /2
Y= -2X-2
and get on the ball and do your own homework lol
2y + 7x + y-1?
x=2y-1
x=1, y=1
2x + 2y = 44x + y = 1There are many methods you can use to solve this system of equations (graphing, elimination, substitution, matrices)...but no matter what method you use, you should get x = -1/3 and y = 7/3.
2y+26 = 28 2y = 28-26 2y = 2 y = 1
