Question

If 4^x-y= 16 and x-2y = 8 is a system of linear equations, then find the value
of x + y.​

Answer 1

Answer:

4x-y=16........... 1

x-2y=8.............. 2

substitute x= 8+2y in eqn 1

4(8+2y) -Y=16

32+8y-y-16=0

7y=-16

y=-16/7

x=8+2(-16/7)

=8-32/7=56-32/7

=24/7

ans: x=-16/7, y=24/7

Answer 2

Answer:

if x+y=16and x-y=4 then x is
