Question

Solve x+3y=16 2x+y=4​ solution find x and y

Answer 1

Step by step explanation:

2x+y=4,

therefore y=4-2x,

putting the value of y in x+3y=16,

x+3(4-2x)=16,

x+12-6x=16,

-5x=16-12,

-5x=4,

x=-4/5,

putting the value of x in 2x+y=4,

2(-4/5)+y=4,

-8/5+y=4,

y=4+8/5,

(20+8)/5,

y=28/5.
