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
To isolate x in the equation 5x + 8 = 63, Randall will first apply the subtraction operation to the constant term, which is 8.
He will subtract 8 from both sides of the equation.
To isolate the variable x in the equation 5x + 8 = 63, Randall needs to perform mathematical operations to manipulate the equation and isolate x on one side of the equation.
The first mathematical operation he should use depends on the goal of isolating x. In this case, Randall should subtract 8 from both sides of the equation.
Here's how to do it step-by-step:
1. Start with the equation 5x + 8 = 63.
2. To eliminate the 8 on the left side of the equation, subtract 8 from both sides of the equation:
(5x + 8) - 8 = 63 - 8.
This simplifies to:
5x = 55.
3. Now, the equation is simplified to 5x = 55.
4. To solve for x, divide both sides of the equation by 5:
(5x)/5 = 55/5.
This simplifies to:
x = 11.
So, Randall will apply the subtraction operation to the 8 on both sides of the equation to isolate x.
