The equation 2y-53 + x = 2 is expressed as y with X___ ．
2y-53 = 2-x, two sides of the equation multiply by 3 to get 2y-5 = 6-3x, transfer term to get 2Y = 11-3x, coefficient to 1 to get y = 11-3x2
The following quadratic equation of two variables is rewritten to express another unknown with an algebraic expression containing one unknown
(1) x-3y=13
(2) 3x+2y=5
(3)4x-5y+6=x+3y-4
(1) x-3y=13
x=3y+13
(2) 3x+2y=5
2y=5-3x
y=1/2*（5-3x）
(3)4x-5y+6=x+3y-4
3x-8y=-10
3x=10-8y
x=1/3*（10-8y）
If x + y = - 2, then y_______ If 3x = 4Y, then y=_________ If 2x-3y = 6=_________ .
y=-x-2
y=3x/4=0.75x
y=2x/3-2
