Use the graphing calculator

found here2y = -x + 12

x = 0.5y + 2

2y = -(0.5y + 2) + 12 {substituted 0.5y + 2, in for x, into top equation}

2y = -0.5y - 2 + 12 {used distributive property}

2.5y = 10 {added 0.5y to each side and combined like terms}

y = 4 {divided each side by 2.5}

x = 0.5y + 2 {bottom original equation}

x = 0.5(4) + 2 {substituted 4, in for y, into bottom original equation}

x = 2 + 2 {multiplied}

x = 4 {added}

**x = 4 and y = 4
