Chapter 2, Problem 15

Solve each equation. 56x2x+43=53\(\frac{5}{6}\)x - 2x + \(\frac{4}{3}\) = \(\frac{5}{3}\)

Verified step by step guidance
1
Start by rewriting the equation clearly: \(\frac{5}{6}x - 2x + \frac{4}{3} = \frac{5}{3}\).
Combine the like terms involving \(x\) on the left side. To do this, express \(-2x\) as a fraction with denominator 6: \(-2x = -\frac{12}{6}x\). Then combine \(\frac{5}{6}x - \frac{12}{6}x\).
Simplify the combined \(x\) terms to get a single fraction coefficient times \(x\). The equation now looks like \(\left(\frac{5}{6} - \frac{12}{6}\right)x + \frac{4}{3} = \frac{5}{3}\).
Isolate the \(x\) term by subtracting \(\frac{4}{3}\) from both sides: \(\left(\frac{5}{6} - \frac{12}{6}\right)x = \frac{5}{3} - \frac{4}{3}\).
Simplify the right side and then solve for \(x\) by dividing both sides by the coefficient of \(x\). This will give you the solution for \(x\).
