Solve using substition

Question

1. The Goofy Goober’s Ice-Cream Shop sells sundaes for $2 and banana splits for $3. On one hot summer day the shop made $156. The total number of sundaes and banana splits they sold that day was 64. Write and solve a system of equations to determine the number of sundaes and the number of banana splits that were sold that day.  

Answer 1

s represents sundaes

b represents banana splits

s + b = 64

2s + 3b = 156

b = 64 - s

2s + 3(64 - s) = 156

Can you solve for s and answer?
