Answer:
Step-by-step explanation:
Let amount of apples be x and oranges be y
<u>Then we have:</u>
<u>Subtract triple of the first equation from the second one:</u>
- 3x + 4y - 3(x + y) = 100 - 3*30
- 3x - 3x + 4y - 3y - 10
- y = 10
<u>Then finding x</u>
So apples = 20, Oranges = 10

Answer:
Bushes are $9.
Bonsai trees are $32.
Step-by-step explanation:
Bushes are b and bonsai trees are t.
15b + 8t = $391
9b + 5t = $241
15b + 8t = $391 × 3 and 9b + 5t = $241 × 5
= 45b + 24t = $1173 and 45b + 25t = $1205
(45b + 24t = $1173) - (45b + 25t = $1205)
t = 1205 - 1173
t = $32
Apply to 15b + 8t = $391.
15b + 32 × 8 = $391
15b = $391 = 32 × 8
15b = $391 - 256
15b = $135
x = ($135 ÷ 15) = $9
