39x + 24(50 - x) = 1,605
<span>13x + 8(50 - x) = 535 </span>
<span>13x + 400 - 8x = 535 </span>
<span>5x = 135 </span>
<span>x = 27 </span>
<span>Answer: 27 of 39-cent stamps were sold</span>
The equation would be y=3x-1
Point Slope Formula:
y - y1 = m(x - x1)
y - 5 = 3(x-2)
y - 5 = 3x - 6
+ 5 + 5
--------------------
y = 3x - 1
Answer:
