To solve for
and 
Naming the first equation as A and second as B.
Using elimination method to solve.
In order to eliminate
we subtract equation A from B.
Subtracting A from B i.e [
(B)
- (A) 
We get, 

Dividing both sides 2.26.

∴ 
We can solve for
by substituting
in equation A.

Subtracting both sides by 52.

∴
