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

1 answer

To isolate \( x \) in the equation \( 5x + 8 = 63 \), Randell will first use subtraction to remove the constant term from the left side. He needs to subtract the \( 8 \) on the left side.

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

This operation will look like this:

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

Which simplifies to:

\[ 5x = 55 \]

Randell can then continue to solve for \( x \).
