It seems that you're asking us to solve the equation for 'y'.
It can be done like this:
3x + 2y = 5 - y
Add 'y' to each side:
3x + 3y = 5
Subtract 3x from each side:
3y = 5 - 3x
Divide each side by 3:
y = 5/3 - x
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
(4, -1)
x = 4 and y = -1 (4. -1)
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
x + 2y = 2.90 => x = 2.90 - 2y Substitue this value of x in the other equation: 3x + 5y = 7.60 3*(2.90 - 2y) + 5y = 7.60 8.70 - 6y + 5y = 7.60 1.10 = y and then substitute this value of y in either equation to find x: x = 2.90 - 2y = 2.90 - 2*1.10 = 2.90 - 2.20 = 0.70 Solution: (x, y) = (0.70, 1.10)
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
(4, -1)
X = -2(13 + y) / 3x = 5y / 4 - 1
x = 4 and y = -1 (4. -1)
5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
Solving for y: 5y = 9 + 2y 5y - 2y = 9 3y = 9 y = 9/3 = 3

3x+5y=48 5y=48-3x-3x+5y=12 -3x+(48-3x)=12-6x=-36x=65y=48-3(6)5y=30y=6(6,6)
x + 2y = 2.90 => x = 2.90 - 2y Substitue this value of x in the other equation: 3x + 5y = 7.60 3*(2.90 - 2y) + 5y = 7.60 8.70 - 6y + 5y = 7.60 1.10 = y and then substitute this value of y in either equation to find x: x = 2.90 - 2y = 2.90 - 2*1.10 = 2.90 - 2.20 = 0.70 Solution: (x, y) = (0.70, 1.10)
