Quinzel and Joseph sell shoes. Last month Quinzel sold 18 less pairs

hichkok12 [17]

Answer:

Quinzel sold 17 pairs of shoes last month.

Step-by-step explanation:

Let be "Q" the number of pairs of shoes Quinzel sold last month and "J" the number of pairs of shoes Joseph sold last month.

Set up a system of equations:

$\left \{ {{Q=J-18} \atop {Q+J=52} \right.$

Solve for "J" from the first equation:

$J=Q+18$

Applying the Substitution Method, you get:

$Q+J=52\\\\Q+(Q+18)=52\\\\2Q=52-18\\\\Q=\frac{34}{2} \\\\Q=17$
