Answer: x = 9 -3y
Step-by-step explanation:
Hi, to answer this question we have to solve the system by substitution:
a)3x − 4y = 12
b)2x + 6y = 18
If we isolate "y" on b)
2x + 6y = 18
2x = 18 -6y
x = 18/2 - 6/2y
x = 9 -3y is a possible equation
Doing the same thing with the other equation a) , and isolating "y" in both expressions, the only possible equation is the one founded above.
