plz rate brainlyist
-5
a^2-25=0
a^2=25
take the square root of both sides
a=5, and -5
I would go about solving this by elimination because the x variables are already the same so all you would have to do is change one equation to the opposite signs and add them, so it would look like:
7y + 5x = 19
+ -3y - 5x = -7
-------------------
4y=12
y=3
Fourteen times two equals twenty-eight, because twenty-eight divided by two equals fourteen
