Understanding the Context
Breaking Down the Equation Step-by-Step
Let’s examine the original equation:
x + (x / 0.7) + 1.4286x = 15
Step 1: Evaluate each term carefully
The term (x / 0.7) simplifies as dividing x by 0.7, which is the same as multiplying x by 1/0.7 ≈ 1.4286.
So:
(x / 0.7) ≈ 1.4286x
Key Insights
Thus, the expression becomes:
x + 1.4286x + 1.4286x = ?
Step 2: Combine like terms
All terms involve x:
- First term: x = 1x
- Second term: 1.4286x
- Third term: 1.4286x
Adding these coefficients:
1 + 1.4286 + 1.4286 = 3.8572
So, the equation simplifies to:
3.8572x = 15
