Question

what is the value of 4x?
21 + 4x = 61
4x = \boxed{}

Explanation:

Step1: Subtract 21 from both sides

To isolate \(4x\), we subtract 21 from each side of the equation \(21 + 4x = 61\). Using the subtraction property of equality, we have \(21 + 4x - 21 = 61 - 21\).

Step2: Simplify both sides

Simplifying the left side, \(21 - 21 + 4x = 4x\). Simplifying the right side, \(61 - 21 = 40\). So, \(4x = 40\).

Answer:

40
