Solving the Equation: (x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87

This article will guide you through the steps to solve the equation (x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87. Let's break down the process:

Step 1: Simplify the Equation

  • Distribute: Multiply the 3 by the terms inside the parentheses: (x) + (x + 3) + (x - 2) + 3x + 9 - 1 = 87

  • Combine like terms: Add all the 'x' terms together and all the constant terms together: x + x + x + 3x + 3 - 2 + 9 - 1 = 87 6x + 9 = 87

Step 2: Isolate the Variable

  • Subtract 9 from both sides: 6x + 9 - 9 = 87 - 9 6x = 78

Step 3: Solve for x

  • Divide both sides by 6: 6x / 6 = 78 / 6 x = 13

Solution

Therefore, the solution to the equation (x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87 is x = 13.

Verification

To verify our solution, we can substitute x = 13 back into the original equation:

(13) + (13 + 3) + (13 - 2) + 3(13 + 3) - 1 = 87

13 + 16 + 11 + 3(16) - 1 = 87

13 + 16 + 11 + 48 - 1 = 87

87 = 87

The equation holds true, confirming that our solution x = 13 is correct.
