8x+11=4x+7

X=

1 answer

To solve the equation \(8x + 11 = 4x + 7\), follow these steps:

  1. Subtract \(4x\) from both sides: \[ 8x - 4x + 11 = 7 \] This simplifies to: \[ 4x + 11 = 7 \]

  2. Next, subtract \(11\) from both sides: \[ 4x = 7 - 11 \] Which simplifies to: \[ 4x = -4 \]

  3. Finally, divide both sides by \(4\): \[ x = \frac{-4}{4} \] This simplifies to: \[ x = -1 \]

So, the solution is \(x = -1\).
