CCSS.6.EE.C.9

Equations with variables on both sides are best solving using....

• Inverse Operations

• Division

• Multiplication

• Parenthesis

Solve the simultaneous equations

x+y=5

x-y=1

• x=2, y=3

• x=3, y=2

• x=3, y=-2

• x=-3, y=2

Identify which method for solving systems is being described by this fact: If one equation is isolated like y = 2x or x = 7 - 4y then this method should be used.

• Graphing

• Substitution

• Elimination (linear combination)

4x + 3y = 9

• y = -3/4x + 3

• y = -4x + 9

• y = -4/3x + 3

• 3y = -4x + 9

Solve for y.  3x + y = 12

• y = -3x +12

• x = y + 4

• x = y + 12

• y = 3x -12
