A) To solve this equation, you would need to fill in the blank with a substitute. Let x represent the unknown number.

=

Next, you would cross multiply.
135 = 45x
Now, the last step would be to isolate the x. To do this, you would divide both sides by 45.
3 = x
= 
b) To solve this equation, you would need to fill in the blank with a substitute. Let x represent the unknown number.

=

Next, you would cross multiply.
18 = 2x
Now, the last step would be to isolate the x. To do this, you would divide both sides by 2.
9 = x
=
I hope this helps!
