Write the word sentence as an equation
27 is 3 times a number y

27=3y

Let’s focus on the wording here.

Is= is in a math equation usually refers to equals. When a number is something, it equals something.

Times= Times in math refers to multiplication. When you times a number by something else, you multiply it.

Now knowing this, let’s substitute these symbols into the equation

27 is 3 times a number y

27=3•y

When with a variable, 3•y will usually just be left 3y. Let’s change this now.

27=3•y

27=3y

This is your final equation! Hope this helps comment below for more questions :)
