5х+(-х)=6+10

To solve the equation \( 5x + (-x) = 6 + 10 \), follow these steps:

1. Simplify both sides of the equation. Start with the right side: \[ 6 + 10 = 16 \] So, the equation becomes: \[ 5x - x = 16 \]

2. Combine like terms on the left side: \[ (5x - x) = 4x \] Thus, the equation simplifies to: \[ 4x = 16 \]

3. Solve for \( x \) by dividing both sides by 4: \[ x = \frac{16}{4} = 4 \]

The solution to the equation \( 5x + (-x) = 6 + 10 \) is \( x = 4 \).
