Answer:
Each shirt cost $<u>7</u>  and each pair of shorts cost $<u>17</u> .
Step-by-step explanation:
let shirts be represented as x
let shorts be represented as y
Younger brother spent $79 on 4 new shirts and 3 pairs of shorts.
4 x + 3 y = $79    .......equation 1
Older brother purchased 7 new shirts and 8 pairs of shorts and paid a total of $185. 
7 x + 8 y = $185  .......equation 2
multiply equation 1 by 7 and equation 2 by -4 and add both equations to get the value of y.
7 × (4 x + 3 y = $79)     ⇒             +28 x + 21 y = $553
-4 × (7 x + 8 y = $185)  ⇒             <u> -28 x - 32 y = - $740</u>
                                                           0   - 11 y   = - $187     ⇒  -11 y   = - $187
y =  ⇒   y = $17
   ⇒   y = $17
shorts = y = $17
put value of y in equation 1
4 x + 3 ( $17 ) = $79  ⇒    4x + $51 = $79   ⇒   4x = $79 - $51
4x = $28   ⇒  x =  ⇒   x = $7
   ⇒   x = $7
Shirts = x = $7

Step-by-step explanation:
6:36 = 6/36 = 1/6
3:18 = 3/18 = 1/6
therefore this ratios are equivalents...
