Answer 1

72÷(X-12)=4 X-12=72÷4 X-12=18 X=18+12 X=30 72÷(30-12)=4 4=4

Answer 2

To solve the equation 72/(x - 12) = 4, we need to isolate the variable x on one side of the equation. Follow these steps:

Step 1: Remove the denominator by multiplying both sides of the equation by (x - 12):

72/(x - 12) * (x - 12) = 4 * (x - 12)

Step 2: Simplify the equation:

72 = 4 * (x - 12)

Step 3: Distribute 4 on the right side of the equation:

72 = 4x - 48

Step 4: Isolate the variable term (4x) by bringing the constant term (-48) to the other side of the equation:

72 + 48 = 4x

Step 5: Combine the constants:

120 = 4x

Step 6: Solve for x by dividing both sides by 4:

x = 120 / 4

Step 7: Calculate the value of x:

x = 30

So, the solution to the equation is x = 30.
