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

(already solved for "y"!)

 

Answer: y = 3x + 5
