Answer
The values of solution for the system are x=4, y=7.
Work Step by Step
To solve
2x + y = 15
(-$\frac{1}{2}$x + y = 5 )$\times$ -1
2x + y = 15
$\frac{1}{2}$x -y = -5 --> add the two equations
2x + $\frac{1}{2}$x = 15-5
$\frac{5}{2}$x = 10
5x = 10(2)
5x =20
x=4
To solve for y
2(4)+y =15
8 + y = 15
y = 15-8
y = 7
