X+ x+ 4+x + 4 = 86

To solve the equation \( X + X + 4 + X + 4 = 86 \), let's first combine like terms.

1. Combine the \( X \) terms: \[ X + X + X = 3X \]

2. Combine the constant terms: \[ 4 + 4 = 8 \]

Now, we can rewrite the equation: \[ 3X + 8 = 86 \]

Next, we can isolate \( 3X \) by subtracting 8 from both sides: \[ 3X = 86 - 8 \] \[ 3X = 78 \]

Now, divide both sides by 3 to solve for \( X \): \[ X = \frac{78}{3} = 26 \]

So, the solution is: \[ X = 26 \]
