Answer:
Step-by-step explanation:
b = pints of blueberries
c = pints of cherry tomatoes
3b + 2c = 28
2b = c
First, substitute 2b into the c of the first equation.
3b + 2(2b) = 28
3b + 4b = 28
7b = 28
b = 4
Then, substitute 4 into the b of the second equation.
2(4) = c
c = 8
Then, substitute both values into the first equation to check.
3(4) + 2(8) = 28
12 + 16 = 28
