<span>3x + 2y = 7
y = –3x + 11
replace </span>y = –3x + 11 into 3x + 2y = 7
3x + 2y = 7
3x + 2(–3x + 11) = 7
3x -6x + 22 = 7
-3x = 7 - 22
-3x = -15
x = 5
<span>y = –3x + 11
y = -3(5) + 11
y = -15 + 11
y = -4
x = 5 and y = -4
answer: </span><span>D. (5, –4)</span>
Answer:
10cm represents $10
2cm represents $2
10cm also represents 1week
