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 answer

To solve the equation \( 5x + 8 = 63 \) by isolating \( x \), Randall's first operation is subtraction. Specifically, he will subtract 8 from both sides of the equation.

Here's how it works step-by-step:

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

  2. Subtract 8 from both sides: \[ 5x + 8 - 8 = 63 - 8 \] This simplifies to: \[ 5x = 55 \]

So, the value Randall will apply the subtraction to is \( 8 \) on the left side of the equation.
