Answer 2

To solve the equation 7*(123-4x) = 729, follow these steps:

Step 1: Simplify the expression on the left-hand side (LHS) of the equation: 7*(123-4x) = 7123 - 74x = 861 - 28x

Step 2: Now, the equation becomes: 861 - 28x = 729

Step 3: Isolate the variable (x) on one side of the equation. To do this, you want to get rid of the constant term on the left side. Since 861 is positive, we will move it to the right side by subtracting 861 from both sides:

861 - 861 - 28x = 729 - 861 -28x = -132

Step 4: Divide both sides by -28 to solve for x:

x = (-132) / (-28) x = 4.71428571429 (approximately)

So, the solution to the equation is: x ≈ 4.71428571429
