Answer 1

Let's write out the problem with the triangles as "x" and the ovals as a number. Since there are 3 triangles and 5 boxes in the first box, the first box would be:

3x+5

In the other box, there are 11 ovals, so:

11

With this, they are equal, so:

3x+5=11

To solve this, move the 5 over onto the other side by subtracting 5 from each side:

3x+5-5 = 11-5

Then you have:

3x = 6

Now, divide doth sides by 3 to isolate x:

3x/3= 6/3

Now you're done!

x=2

Hope that helps.
