I solved this rational equation by combining expressions and isolating the variable a
a = -2
Its proportion,
For 5 stops, its 11.
So, for 3 stops how many ??
5:11 :: 3:?
5/11 = 3/?
? = 3 × 11/5
? = 33/5 = 6.6 ≈ 7 packages
Tom will get 166
Ben will get 581

Since both equations give the value of y, therefor y = y. You simply substitute y with its corresponding equation.
y = y
x + 9 = 2x + 1 *we need to find the value of x to get the value of y.
x - 2x = 1 - 9
-x = -8
-1x/-1 = -8/-1
x = 8
Substitute x with its value to get y.
Equation S: y = x + 9 </span>⇒ y = 8 + 9 ⇒ y = 17
Equation T: y = 2x + 1 ⇒ y = 2(8) + 1 ⇒ y = 16 + 1 ⇒ y = 17
<span>x+9=2x+1
</span>17 = 17
