Solving the Equation: (x) + (x+3) + (x-2) + 3(x+3) - 1 = 87
This article will guide you through the process of solving the equation (x) + (x+3) + (x-2) + 3(x+3) - 1 = 87.
Step 1: Simplify the Equation
First, we need to simplify the equation by combining like terms.
- Distribute the 3: 3(x+3) = 3x + 9
- Combine x terms: x + x + x + 3x = 6x
- Combine constant terms: 3 - 2 + 9 - 1 = 9
The simplified equation is now: 6x + 9 = 87
Step 2: Isolate the Variable
To isolate the variable 'x', we need to get rid of the constant term (+9). We can do this by subtracting 9 from both sides of the equation:
- 6x + 9 - 9 = 87 - 9
- 6x = 78
Step 3: Solve for x
Now, we have 6x = 78. To find the value of x, we need to divide both sides of the equation 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.
