Answer:

3x + 4 = 5x

Explanation:

Another way of writing "Three times a number, x" is "3x". That's because 3x is actually 3 multiplied by x.

Another way of writing "increased by fou" is "+ 4". That is because increasing something means adding on.

Another way of writing "five times the number, x" is "5x". That is because 5x is actually 5 multiplied by x.

So we have "3x + 4" and "5x". We know they are equal to each other because of the question so, 3x + 4 = 5x is our equation.
