3(7+4х)-8х=201

Let's solve the equation step by step:

Given:
\[ 3(7 + 4x) - 8x = 201 \]

1. Distribute the 3: \[ 3 \times 7 + 3 \times 4x - 8x = 201 \] \[ 21 + 12x - 8x = 201 \]

2. Combine like terms (\(12x - 8x\)): \[ 21 + 4x = 201 \]

3. Subtract 21 from both sides: \[ 4x = 201 - 21 \] \[ 4x = 180 \]

4. Divide both sides by 4: \[ x = \frac{180}{4} \] \[ x = 45 \]

So, the solution is: \[ x = 45 \]
