What is the solution to this system of equations?
3x + y = 17
x + 2y = 49

y=26, x=-3

Step-by-step explanation:

3x+y=17

3x+y-y=17-y

3x=17-y

Divide both sides by 3

Simplify

\frac{17-y}{3}+2y=49

\frac{17-y}{3}\cdot \:3+2y\cdot \:3=49\cdot \:3

17-y+6y=147

17+5y=147

17+5y-17=147-17

5y=130

\frac{5y}{5}=\frac{130}{5}

y=26

x=\frac{17-26}{3}

x=-3
