Question

Please help in the calculation of these linear equations

Answer 1

Step-by-step explanation:

2x+y=8....... (1)

x+2y=8...... (2)

multiple eq (1) throughout by 2

4x+2y=16..... (3)

substract eq 2 and 3

4x+2y=16

- x+2y=8

= 3x =24

x=24/3

x=8

substitute x=8 in equation (1)

2x+y=8

2(8)+y=8

16+y=8

y=16/8

y=2
