## Intermediate Algebra (12th Edition)

$x=1$ $y=2$
Equation 2 is already solved for y, we substitute y in the first equation, with the expression in the second: $4x+y=6$ $4x+2x=6$ $x=1$ $y=2x=2$ We need to check, if it is the right solution, we substitute x with 1 and y with 2: $4(1)+2=6$ $\checkmark$ $2=2(1)$ $\checkmark$
