Answer:
Step-by-step explanation:
4s + 2j = 68........2j = -4s + 68........j = -2s + 34
3s + 3j = 81
3s + 3(-2s + 34) = 81
3s - 6s + 102 = 81
3s - 6s = 81 - 102
-3s = - 21
s = -21/-3
s = 7 <==== shirts cost 7 bucks
j = -2s + 34
j = -2(7) + 34
j = -14 + 34
j = 20 <===== jeans cost 20 bucks

The 2md number can be y. This makes the first number 1/5 of y
Your equation is y + 1/5y = 30
You can randomly plug in numbers and you get that the first number is 5. This means that the second number is 25
