3a+b=52a+5=10use elimination to solve each systems of equations.

Answer 1

The way you typed it, there is no need to use elimination
from 52a+5 = 10
52a = 5
a = 5/52

sub into 3a + b = 10
3(5/52) + b = 10
times 52
15 + 52b = 520
52b = 505
b = 505/52

Whatever would make me think that you have a typo
