Term
 Solve the linear equation for "y"   3x + 2y = 8
Definition
 3x + 2y = 8 (Subtract 3x from both sides) 2y = -3x + 8 (Divide everything by 2) y = (-3/2)x + 4 Answer: y = (-3/2)x + 4
Term
 Solve the linear equation for "y"   2x - y = 5
Definition
 2x - y = 5 (Subtract 2x from both sides) -y = -2x + 5 (Divide everything by -1) y = 2x - 5   Answer: y = 2x - 5
Term
 Solve the linear equation for "y" 12x + 6y = 12
Definition
 -12x + 6y = 12 (Add 12x to both sides) 6y = 12x + 12 (Divide everything by 6) y = 2x + 2 Answer: y = 2x + 2
Term
 Solve the linear equation for "y"   x - y = 3
Definition
 x - y = 3 (Subtract x from both sides) -y = -x + 3 (Divide both sides by -1) y = x - 3   Answer: y = x - 3
Term
 Solve the linear equation for "y"   y - 2x = 3
Definition
 y - 2x = 3 (Add 2x to both sides) y = 2x + 3   Answer: y = 2x + 3
Term
 Solve the linear equation for "y"   -4x +2y = 5
Definition
 -4x + 2y = 5 (Add 4x to both sides) 2y = 4x + 5 (Divide both sides by 2) y = (4/2)x + (5/2) (Simplify) y = 2x + (5/2)   Answer: y = 2x + (5/2)
Term
 Solve the linear equation for "y"   3 + y = 5x
Definition
 3 + y = 5x (Subtract 3 from both sides) y = 5x - 3 Answer: y = 5x - 3
Term
 Solve the linear equation for "y"   -5 - y = x
Definition
 -5 - y = x (Add 5 to both sides) -y = x + 5 (Divide everything by a -1) y = -x - 5   Answer: y = -x - 5
Term
 Solve the linear equation for "y" -x - 2y = -6
Definition
 -x - 2y = -6 (Add x to both sides) -2y = x - 6 (Divide everything by a -2) y = (-1/2)x + 3   Answer: y = (-1/2)x + 3
Term
 Solve the linear equation for "y"   5 + 3x = y
Definition

5 + 3x = y
