Method #1: Substitution Method

Method #1: Substitution Method. Example 1. Solve using substitution. x= 4y x+3y=-21. x + 3y = -21. x = 4y. 4y + 3y = -21. x = 4(-3). 7y = -21. x = -12. y = -3. (-12,-3). EXAMPLE 1:. x= 4y x+3y=-21. Check solution ( -12,-3). x=4y -12=4(-3) -12=-12. x+3y=-21 -12+3(-3)=-21
