Randall needs to solve the equation 5x + 8 = 63

. His first mathematical operation used to isolate x
is subtraction. Which value will he apply it to?(1 point)

1 answer

To isolate \( x \) in the equation \( 5x + 8 = 63 \), Randall should subtract 8 from both sides of the equation. So, he will apply the subtraction to the value 8.

Here's how it looks step by step:

  1. Start with the equation: \[ 5x + 8 = 63 \]

  2. Subtract 8 from both sides: \[ 5x + 8 - 8 = 63 - 8 \]

  3. This simplifies to: \[ 5x = 55 \]

So, the value Randall applies the subtraction to is 8.
