Note: in the 2nd eqn we are given a formula for x: x = 2y-15. Sub this result into the first eqn; doing so will eliminate x:
-5(2y-15)+4y =3
-10y + 75 + 4y = 3, so -6y = -72. Then y = 12. Solution is (9,12).
Check this by subst.:
Is -5(9)+4(12) = 3?
Is -45 + 48 = 3? YES.
(5, 3) is your answer hope this helps!
Answer:
Hello, it seems my fellow Josh needs some help, so here we go. It's quite simple, the answer is 8.
Step-by-step explanation:
12 - 4 = 8
or 8 + 4 = 12.
So he practiced 8 times in public, or to others.
OH SO LIKE CHESTER WAS A REALLY BAD PERSON.
