\qquad\qquad\huge\underline{{\sf Answer}}

Let's solve for x ~

\qquad \tt  \dashrightarrow \: 4(3 + x) + x = x + 4

\qquad \tt  \dashrightarrow \: 12 + 4x+ x = x + 4

\qquad \tt  \dashrightarrow \: 5x + 12 = x + 4

\qquad \tt  \dashrightarrow \: 5x  - x =  4 - 12

\qquad \tt  \dashrightarrow \: 4x =  - 8

\qquad \tt  \dashrightarrow \: x =  - 8  \div 4

\qquad   \dashrightarrow \: \boxed{  \tt x =  - 2 }

\bold{Hello!}

\large \sf \dagger \: {Explanation \: \dagger  }

<em>Let's solve for x ~</em>

<em />

<em />\sf{4(3 \: + \: x) \: + \: x = x \: + \: 4}

Step 1: Simplify both sides of the equation.

\sf{4(3 \: + \: x) \: + \: x = x \: + \: 4}

\sf{(4)(3) \: + \: (4)(x) \: + \: x = x \: + \: 4} \: (Distribute)

\sf{12 \: + \: 4x \: + \: x  = x \: + \: 4}

\sf{(4x \: + \: x) \: + \: (12) = x \: + \: 4} \: (Combine \: Like \: Terms)

\sf{5x \: + \: 12 = x \: + \: 4}

\sf{5x \: + \: 12 = x \: + \: 4}

Step 2: Subtract x from both sides.

\sf{5x \: + \: 12 \: - \: x = x \: + \: 4 \: - \: x}

\sf{4x \: + \: 12 = 4}

Step 3: Subtract 12 from both sides.

\sf{4x \: + \: 12 \: - \: 12 = 4 \: - \: 12}

\sf{4x = -8}

Step 4: Divide both sides by 4.

\sf{\frac{4x}{4} = \frac{-8}{4}

\sf{x = -2}
