See Explanation
Explanation:
Please note that I'll replace all � with +
1. |10|
This implies the absolute value of 10 and it always returns the positive value;
Hence;

2. |-4|
Using the same law applied in (1)

3. 5/8 - 3/8 = ?
Take LCM

Subtract the numerator

Divide the numerator and denominator by 2

Hence:

4. 7/8 - 5/6
Take LCM


Hence;

5. 6 * (-7/2)

Multiply the numerator


Hence:

5. 6/5 /(-12/25)

Change the divide to multiplication

Divide 6 and 12 by 6

Divide 5 and 25 by 5


Hence;

6. 3 + 4^2 * 2

Solve the exponent

Apply B.O.D.M.A.S



7. 2/3 + 5/6

Apply LCM


Divide the numerator and denominator by 3

Convert to mixed fraction

Hence;

8. 16 - 12/(-4)

Solve the fraction

Open the bracket


Hence;

9. -9(3w + x + 2)

Open brackets: Distributive property


Hence;

10. -2(w + 2) + 5w

Open bracket: using distributive property


Collect Like Terms


Hence;

11. 16x^2 + 8 + 10x + 2x^2 + 14x

Collect Like Terms


Expand the expression

Factorize:


Hence;

12. b = -5 and y = 6

Substitute -5 for b and 6 for y



Hence;

13. y = -3

Substitute -3 for y

Open all brackets


Hence;

14.
