Question

The equation below shows the cost, in dollars, of a T-shirt, selling at $12.00, and 3 pairs of socks. What is the cost of one pair of socks, s? 12 + 3s = 42

Answer 1

12+3s=42. 12+3(10)=42
-12 -12. 12+30 =42
3s. = 30. 42=42 ✔️
/3. /3
S. =. 10
The answer is s=10

Answer 2

The answer is one pair of socks = $10

Explanation:

I subtracted 42 by 12 and got 30. I then divided 30 and 3 and got 10.

42-12=30

30/3=10

Or you can subtract 12 from both sides to get the variable on one side. Then you divide the variable by the coefficient (3) and divide 30 by 3 to get 10.
