Answer:The correct answer is x = 5 2/3 - 7 2y/3Step-by-step explanation:1. Let's solve the equation for x3x + 23y = 173x = 17 - 23y (Subtracting 23y at both sides)3x/3 = 17/3 - 23y/3 (Dividing by 3 at both sides)x = 17/3 - 23y/32. Proof of 17/3 - 23y/3 as the value of x3x + 23y = 173(17/3 - 23y/3) + 23y = 17 (Multiplying the values inside the parenthesis)17 - 23y + 23y = 1717 = 17It has been proved that x = 17/3 - 23y/33. However we can simplify17/3 - 23y/35 2/3 - 7 2y/3There isn't a system of equations that will allow us to find y
