Question: Solve the following equations:

\[\begin{align} & x-y-5=0 \\ & 2x-y+17=0 \\ \end{align}\]

\[\begin{align} & x-y-5=0 \\ & 2x-y+17=0 \\ \end{align}\]

0

**Question: **Given the system of equations below, solve using any appropriate method:

3x + 6y = 21

-5x + y = 20

**Question: **The sum of two numbers is twenty. Using *x* to represent the smaller of the two numbers, translate "the difference between two more than the larger number and twice the smaller number" into a variable expression. Then simplify.

**Question: **Solve: \[5\left[ 2-\left( 2x-4 \right) \right]=2\left( 5-3x \right)\]

**Question: **Solve: \[3\left[ 4-2\left( x-2 \right) \right]=3\left( 2-4x \right)\]

**Question: **Solve: \[\frac{7}{12}=\frac{2}{3}x+\frac{3}{4}\]

**Question: **Evaluate: \[{{\left( a-4b \right)}^{2}}\div {{c}^{3}}\] when \[a=4,\,\,b=-1,\,\,c=-2\]
