Substitution Method

Solving Systems of Linear Equations

Open Ended

Write a new equation after replacing one variable with the other variable in the problem. (Hint: replace the y's).

Multiple Choice

Write the new equation to solve after using the substitution process correctly for the system.

y = 5x - 7

-3x - 2y= -12

• -3(5x - 7) - 2y= -12

• -3x - 2(5x-7) = -12

• -3x -2y = 12(5x-7)

Multiple Choice

Write the new equation to solve after using the substitution process correctly for the system.

y = x - 1

2x - 3y= -1

• 2(x-1) - 3y= -1

• 2x - 3(x-1) = -1

• 2x -3y = 12(x-1)
