Answer 1

Answer:

2 strawberry

4 blackberry

Step-by-step explanation:

s = number of strawberry pies

b = number of blackberry pies

s + b = 6, then s = 6 - b

9s + 8b = 50

substitute for s:

9(6 - b) + 8b = 50

54 - 9b + 8b = 50

54 - b = 50

subtract 54 from each side of the equation:

-b = -4

multiple both side by -1:

b = 4

s = 6 - 4 = 2
