Q2. Look at the picture.

Q3.
Put the value of x = 2 to the equation 3x + y = 5:

<em>subtract 6 from both sides</em>

Q4.

Substitute (*) to (**):
<em>use distributive property</em>

<em>add 33 to both sides</em>
<em>divide both sides by 11</em>

Put the value of m to (*):


Q5.
w - width
3w - length
24 in - the sum of length and width
The equation:

<em>divide both sides by 4</em>



12 x 2 = 24 (Julio), 24 x 4 = 96 (David).
