• Problem:(answer,level of difficulty(easy, medium, hard))
• Example 2x=6: (x=3,easy)
1. (5 + x)^2 where x=4 (easy)
2. 3*3+4 (easy)
3. 2x–(2x+3) where x=.5 (medium)

## Section A (5 marks)

1. $24 \div 6 - 7 =$
2. $(5 + 3) \times 6=$
3. $\frac{16+14}{5} - 3=$
4. $\frac{36}{4 - (-2)}+5=$
5. $(\frac{2 \times 27}{9})^2=$

## Section B (5 marks)

Evaluate the following expressions.

1. $9+3^2=$
2. $3+ \frac{20}{2^2} =$
3. $\frac {2(3+4)}){94^0}=$
4. $20 - 2(\frac{96}{4^2})=$
5. $-4 + 5(\frac{56+7}{3^2}) - 1 =$

## Section C (5 marks)

Evaluate the following expressions when $w=4$, $x=5$, $y=6$ and $z=7$.

1. $3x+2y+z=$
2. $\frac{w^2}{y+2}+2z=$
3. $2(\frac{x^2+3}{w})-(2y-z)=$
4. $(6-3)(\frac{2w-x}{z-4})+(3y-4)=$
5. $3^2(2w^0)(\frac{wx}{y-2})-z=$

## Section D (5 marks)

Evaluate the value of $x$ in the following equations with the given value of $y$.

1. $4x+3y=18$ (given $y=2$)
2. $\frac{2x}{y+1}+4=20$ (given $y=3$)
3. $2(\frac{2x-2}{y-3}+8=6^2$ (given $y=7$)
4. $3^3+2^0+3x-2y(\frac{18}{2})=97$ (given $y=3$)
5. $[5(2x-3)]^2=y+6$ (given $y=19$)
