Write 25 less than a number 4 as an expression​

y - 25 = 4

Step-by-step explanation:

i’m guessing you meant this as “25 less than a number = 4.” so i can put tha as an expression.

Basically you’re gonna want to take the unknown number and turn it into a variable.

You should know what a variable is but if not it’s just a letter in place for an unknown number.

so since the unknown number, we will use the letter y as the variable.

so y-25=4

boom that’s it.

since there’s an unknown number in place of the bigger number, we can just put the variable and write the rest out as a regular problem.

and if you need to know the variable number it’s 29.
