Solution Steps
To solve the equation \(4(3x - 8) - 2 = 4(x - 2) + 14\), we will first expand both sides of the equation. Then, we will collect like terms and isolate the variable \(x\) on one side of the equation. Finally, we will solve for \(x\) and verify the solution by substituting it back into the original equation.
Step 1: Expand and Simplify the Equation
We start with the equation:
\[
4(3x - 8) - 2 = 4(x - 2) + 14
\]
Expanding both sides gives:
\[
12x - 32 - 2 = 4x - 8 + 14
\]
This simplifies to:
\[
12x - 34 = 4x + 6
\]
Step 2: Isolate the Variable
Next, we isolate \(x\) by moving all terms involving \(x\) to one side and constant terms to the other:
\[
12x - 4x = 6 + 34
\]
This simplifies to:
\[
8x = 40
\]
Step 3: Solve for \(x\)
Dividing both sides by 8 gives:
\[
x = \frac{40}{8} = 5
\]
Step 4: Verify the Solution
To verify, we substitute \(x = 5\) back into the original equation:
\[
4(3(5) - 8) - 2 = 4(5 - 2) + 14
\]
Calculating both sides:
Left side:
\[
4(15 - 8) - 2 = 4(7) - 2 = 28 - 2 = 26
\]
Right side:
\[
4(3) + 14 = 12 + 14 = 26
\]
Since both sides are equal, the solution is verified.
