The expression inside the absolute value can be either positive or negative.

above, they solved for x in the positive expression. x/2 + 3 = 2

solve for x in the negative expression.
x/2 + 3 = -2
x/2 = -2 - 3
x/2 = -5

4) Let the number be : N

Given : 10% of this number is 25

$\sf{\implies 10\% \ of \ N = 25}$

$\sf{\implies \dfrac{10}{100} \times N = 25}$

$\sf{\implies \dfrac{N}{10} = 25}$

$\sf{\implies N = 250}$

Now we need to find 60% of 250

$\sf{\implies \dfrac{60}{100} \times 250}$

$\sf{\implies 6 \times 25}$

$\sf{\implies 150}$

5) Given : James left the home at 10 : 00 AM

First : He will meet his friend Tom at the skate park which is 15 minutes walk from his home.

So, James reached the skate park 10 : 15 AM

Second : They stayed at the skate park for an hour

So, till 11 : 15 AM James and Tom were at skate park

Third : Then they will take a 10 minutes walk over to the Burger bar

So, James and Tom reached the Burger bar at 11 : 25 AM

6) First let us find 75% of 80

$\sf{\implies \dfrac{75}{100} \times 80}$

$\sf{\implies 15 \times 4}$

$\sf{\implies 60}$

Now let us find 40% of 30

$\sf{\implies \dfrac{40}{100} \times 30}$

$\sf{\implies 12}$

Now, (60 - 12) = 48

<u>Answer:</u> 75% of 80 is 48 greater than 40% of 30

7) Given : Journey to school takes 70 minutes

We know that : 1 hour = 60 minutes
