Question

Write as an algebraic expression.

4 less than d
Tell what can be done to each side of the equation to get the variable alone on one side of the equal sign.

Answer 1

Answer:d-4

Step-by-step explanation: To get the variable alone on one side of the equal sign, you can add or subtract the same value from both sides of the equation. In this case, to isolate the variable 'd' on one side, you can add 4 to both sides:

d - 4 + 4 = d

This simplifies to:

d = d

By doing this, the variable 'd' remains alone on one side of the equation.
