The expression "-b + 3x" represents a mathematical expression for which we need values assigned to variables to calculate a specific value.
2w+14=48
To solve the equation 2w + 14 = 48, we need to isolate the variable w. Here's how to do it step by step:

1. Start with the equation: 2w + 14 = 48

2. Subtract 14 from both sides of the equation to isolate the term with w:
2w + 14 - 14 = 48 - 14
2w = 34

3. Divide both sides of the equation by 2 to solve for w:
2w/2 = 34/2
w = 17

Therefore, the solution to the equation 2w + 14 = 48 is w = 17.

To find out how many minutes Emma spent studying, we need to multiply the amount Sarah spent by 112.

Sarah's studying time: 3512 minutes

Emma's studying time: 3512 * 112 = 393,344 minutes

Therefore, Emma spent 393,344 minutes studying.
