We have a system of 2 linear equations with 2 unknown, so we can solve it: <span> 2x + y = 5 -3x + 2y = 17 We'll use substitution, so lets solve for y in the first equation and substitute that in the second afterwards: y = 5 - 2x </span>-3x + 2(5 - 2x) = 17 -3x + 10 - 4x = 17 -7x = 7 x = -1 then substitute in the original equation to find y: <span>y = 5 - 2x = 5 - 2(-1) </span>= 5 + 2 y = 7
