An algebraic expression that represent how much Mr. Green paid in all is 3(m + 1) + d
<h3 /><h3>Pet fish</h3>
The following represents the items bought
- Each bag has m mollies and 1 bala
- He bought 3 of these bags
The expression that represents the items in a bag is:

<h3>Fish food</h3>
A box costs d dollars.
This means that, the total amount Mr Green spent in the store is:

Let's get the same terms on the same side.
I am going to remove 5x from both sides of the equation by subtracting 5x
5x - 5x<span> -7 = 7x -</span>5x<span> - 17</span>
-7 = 2x - 17 now lets remove the 17 from both sides
-7 + 17 = 2x (why do we add 17? Think of 2x -17 as 2x + -17. Tor remove a negative number we add it.
Now we finally have 10=2x and if we divide both sides by 2
<u>10</u><span> = </span><u>2x</u><u>
</u>2 2 we get that x = 5
<u />Let's check by substituting 5 in the original equation:
5(5) - 7 = 7(5) - 17
25 - 7 = 35 - 17
<span>18 = 18</span>
