Answer 2

Equation: 4(х-3)=х+9

To solve the equation 4(х-3)=х+9, we can follow these steps:

Step 1: Distribute the 4 on the left side of the equation: - 4 * х - 4 * 3 = х + 9 - 4х - 12 = х + 9

Step 2: Simplify the equation by combining like terms: - 4х - х = 9 + 12 - 3х = 21

Step 3: Solve for х by dividing both sides of the equation by 3: - х = 21 / 3 - х = 7

Therefore, the solution to the equation 4(х-3)=х+9 is х = 7.
