Answer: $x = 9$

Step-by-step solution

Step 1: Expand brackets on both sides

Apply the distributive property $a(b + c) = ab + ac$ to remove the parentheses on both sides of the equation. On the left side, multiply $3$ with $x$ and $-2$ to get $3x - 6$ . On the right side, multiply $2$ with $x$ and $4$ to get $2x + 8$ .

Step 2: Combine constant terms on the left side

Simplify the constant terms on the left-hand side: $-6 + 5 = -1$ . The equation now becomes $3x - 1 = 2x + 8$ .

Step 3: Transpose the variable term to the left

Subtract $2x$ from both sides to collect all terms containing the variable $x$ on the left side. Since $3x - 2x = x$ , we obtain $x - 1 = 8$ .

Step 4: Isolate x

Transpose $-1$ to the right side by adding $1$ to both sides. This gives $x = 8 + 1 = 9$ .
