Hello from MrBillDoesMath!
Answer:
x = 80/3 ( 26 2/3)
y = 11
Discussion:
Step 1:
-2 + y = 9 => add 2 to both sides
2 + -2 + y = 9 +2 =>
y = 11
Step 2:
Substitute y = 11 (from Step 1) into
3x - 7y = 3 =>
3x - 7(11) = 3 => y = 11 from Step 1
3x - 77 = 3 => add 77 to both sides
3x - 77 + 77 = 3 + 77 =>
3x = 80 =>
x = 80/3
Thank you,
MrB
