Hi there !
We have to use elimination method
5x + 2y = 29 ----> [ 1 ]
x + 4y = 13 ----> [ 2 ]
Multiplying equation [ 1 ] with 2
10x + 4y = 58 -----> [ 3 ]
Subtracting equation 2 from 3
10x + 4y = 58
x + 4y = 13
----------------------------------------------
9 x = 45
x = 45/9
x = 5
x + 4y = 13
5 + 4y = 13
4y = 13-5
4y = 8
y = 2
