Answer:
$7; Cost of a box of apples (x)
$13; Cost of a box of oranges (y)
Step-by-step explanation:
Matt: 3x + 14y = 203 3(-y + 20) + 14y = 203 3x + 14(13) = 203
Ming: 11x + 11y = 220 -3y + 60 + 14y = 203 3x + 182 = 203
11x = -11 11y = 143 3x = 21
x = -y + 20 y = 13 x = 7
Answer:
x = 1
Step-by-step explanation:
3x + 1/2 (2x + 6) = 6x + 1
3x + x + 3 = 6x + 1
4x + 3 = 6x + 1
2 = 2x
x = 1
