Chapter 6: Problem 16

Solve and check each equation. \(5 x-8=72\)

Short Answer

Expert verified
The solution to the equation \(5x - 8 = 72\) is \(x = 16\).

Step by step solution

01

Set up the equation

The equation given in the problem is \(5x - 8 = 72\).
02

Isolate the variable

To solve for \(x\), first, add 8 to both sides of the equation. This gives \(5x = 72 + 8\), which simplifies to \(5x = 80\).
03

Solve for \(x\)

Next, we just divide both sides by 5. This gives \(x = 80 / 5 = 16.\)
04

Check the solution

After obtaining the value of \(x\), it's important to verify by substituting \(x = 16\) back into the original equation \(5x - 8 = 72\). With \(x = 16\), the left side becomes \(5(16) - 8 = 80 - 8 = 72\), which is equal to the right side, so our solution is correct.
