Hi,

x + y = 350                    (equation 1)

3x + 2y = 950                 (equation 2)


Use Substitution Method

Isolate variable x in equation 1


x = 350 – y                     (equation 3)


Substitute equation 3 into equation 2


3(350 – y) + 2y = 950

1050 – 3y + 2y = 950

3y – 2y = 1050 – 950

y = 100


Substitute y = 100 into equation 1


x + 100 = 350

x = 250


Answer: 250 $3 tickets and 100 $2 tickets were sold.
