Answer:
Flip flops = 5
Sneakers = 2
Step-by-step explanation:
Let
x = flip flops
y = sneakers
x + y = 7 (1)
15x + 28y = 131 (2)
From (1)
x = 7 -y
Substitute x = 7 - y into (2)
15x + 28y = 131
15(7 - y) + 28y = 131
105 - 15y + 28y = 131
-15y + 28y = 131 - 105
13y = 26
y = 26/13
= 2
y = 2
Substitute y = 2 into (1)
x + y = 7
x + 2 = 7
x = 7 - 2
= 5
x = 5
Flip flops = 5
Sneakers = 2
Answer:
Eight
Step-by-step explanation:
We have two conditions:
(1) C + D = 12
(2) 2C + 3D = 32 Subtract D from each side of Equation (1)
C = 12 - D Multiply both sides by 5
2(12 – D) + 3D = 32 Remove parentheses
24 – 2D + 3D = 32 Combine like terms
24 + D = 32 Subtract D from each side
D = 8
