Solve this equation for x.

x + 5y = -9

Mathematical Equivalence

ON

Solve the system by substitution.

-8x + y = 21 and -4x - 6y = -22

• x = -3, y = -3

• x = -2, y = 5

• x = -1, y = 13

• x = 0, y = 21

What is the sum of these two equations?

8x + 2y = 4

-8x + 12y = 52

Mathematical Equivalence

OFF

Solve using the elimination method.

x - y = 11

2x + y = 19
