Question

$x + y = 4 \: and \: 2x + y = 6$Sketch and estimate the solution.

Answer 1

Do you have a picture of your question?

It's because I am not sure about the equations

ok

x + y = 4 2x + y = 6

x y x y

-2 6 -2 10

0 4 0 6

2 2 2 2

Graph the points

The solution is where both lines intercept (2, 2)
