What Variable can we eliminate?

-6x + 5y = 1

6x + 4y = -10

• x

• y

What is the result when you add the two equations?

-6x + 5y = 1

6x + 4y = -10

• 12x = -9

• 12x + 9y = -9

• 9y = 9

• 9y = -9

-6x + 5y = 1

6x + 4y = -10

When you add the two equations the resulting equation is 9y = -9,

solve for y

• y = 9

• y = -9

• y = -1

• y =1

-6x + 5y = 1

6x + 4y = -10

Substitute the value for y in and solve for the value of x

• x = -10

• x = 10

• x = -1

• x =1

Write the solution as an ordered pair

-6x + 5y = 1

6x + 4y = -10

• (-1,7/5)

• (0,-1)

• (1,1)

• (-1,-1)
