Question

solve this linear equation in graph : x+3y=16 ; 2x-y=4

Answer 1

Answer:

x=4 and y=4

Step-by-step explanation:

sol, we have x+3y=16

2x-y=4

equqtion(1) becomes x=16-3y

substituting the above relation of x in(2)and we got

2(16-3y)-y=4

32-6y-y=4

-6y-y=4=32

-7y= -28

y=-28÷-7=4

substituting y=4 in eq

16-3(4)

the solution is x=4 and y=4
