3 x + 2 y = 5 2 y = − 3 x + 5 y = − 2 3 x + 2 5
3x + 2y = 5 :Subtract the 3x over to the other side
2y = -3x + 5 :Then, divide the whole equation by 2
y = -3/2x + 5/2
To solve for y in the equation 3 x + 2 y = 5 , we first isolate y by moving 3 x to the other side, resulting in 2 y = 5 − 3 x . Then, we divide by 2 to find y = 2 5 − 3 x . This represents y in terms of x .
