Please solve this problem.
just olya [345]

x=number of oranges.

y=number of bananas.

$5

we can suggest this system of equations:

x+y=12

0.5x+0.25y=5

We can solve this system of equations by substitution method.

x=12-y

0.5(12-y)+0.25y=5

6-0.5y+0.25y=5

-0.25y=5-6

-0.25y=-1

y=-1 /- 0.25=4

x=12-y

x=12-4=8

Answer:

<em>Tanya bought 8 oranges and 4 bananas.</em>
