Randall needs to solve the equation 5x + 8 = 63. His first mathematical operation used to isolate x is subtraction. Which value will he apply to it?

Answer 1

To isolate \( x \) in the equation \( 5x + 8 = 63 \), Randall will first use subtraction to eliminate the constant term on the left side.

He will subtract \( 8 \) from both sides of the equation. This gives:

\[ 5x + 8 - 8 = 63 - 8 \]

Simplifying this, we have:

\[ 5x = 55 \]

So, the value he will apply for subtraction is \( 8 \).
