Answer:
Second equation:
-x + 3y = 6
Multiply the second equation by 4 on both sides:
-4x + 12y = 26
Step-by-step explanation:
Answer:
-3x + 9y = 18
Step-by-step explanation:
4x - 9y = 9
-x + 3y = 6
Multiply both sides of the second equation by 3 to eliminate the variable y after adding the equations.
-3x + 9y = 18
