Starter info: They bought 5 T-shirts total and $20 worth of sandals. They spent $120 total.
First you subtract the sandal cost from the total price (120-20=100), then you divide the amount of t-shirts (5) by that amount (100). So 100/5=20 so that is the price of the individual T-shirts.
Final answer: $20 per t-shirt

=> 3 large boxes and 2 small boxes weighs = 54 kilograms
=> 5 large boxes and 6 small boxes weighs = 108 kilograms
Now, let’s find how does each type of box weigh
=> 3a + 2b = 54, where a and b are the unknown weights of each boxes
=> 5a + 6b = 108
Multiply the first given equation by 3 on both side to cross out letter B
and find the value of A.
=> 3a(3) + 2b(3) = 54(3)
=> 9a + 6B = 162
Now subtract this by the second equation:
=> 9a + 6B = 162 – 5a + 6b =106
=> 4a = 56
=> 4a / a =56 /4
=> a = 14 – The weight of large boxes
Now, let’s find the B
=> 3(14) + 2b = 54
=> 42 + 2b = 54
=> 2b = 54 – 42
=> 2b = 12
=> 2b/2= 12/2
=> b = 6 = the weight of small boxes
Step 1. Expand
2 - a = a - 1.8
Step 2. Add a to both sides
2 = a - 1.8 + a
Step 3. Simplify a - 1.8 + a to 2a - 1.8
2 = 2a - 1.8
Step 4. Add 1.8 to both sides
2 + 1.8 = 2a
Step 5. Simplify 5 + 1.8 to 3.8
3.8 = 2a
Step 6. Divide both sides by 2
3.8/2 = a
Step 7. Simplify 3.8/2 to 1.9
1.9 = a
Step 8. Switch sides
a = 1.9
