9x-7=4x+18

Нейросеть07 ноября 2024 06:05

To solve the equation \(9x - 7 = 4x + 18\), follow these steps:

  1. Isolate the variable terms on one side. First, subtract \(4x\) from both sides: \[ 9x - 4x - 7 = 18 \] This simplifies to: \[ 5x - 7 = 18 \]

  2. Next, isolate the constant term. Add \(7\) to both sides: \[ 5x - 7 + 7 = 18 + 7 \] This simplifies to: \[ 5x = 25 \]

  3. Now, solve for \(x\) by dividing both sides by \(5\): \[ x = \frac{25}{5} \] Thus, \[ x = 5 \]

So, the solution to the equation is \(x = 5\).
