Q:
# Use the substitution method to solve the system of equations. Choose the correct ordered pair. x + 3y = 9 y = x β 5

Accepted Solution

A:

substitute y for x-5 getting x+3(x-5)=9

use distributive axiom getting x+3x-15=9

combine like terms getting 4x-15=9

add 15 to both sides getting 4x=24

divide by 4 getting: x=6

substitute x into y=x-5 getting y=6-5

combine like terms: y=1 x=6. thatβs your answer.
