Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

$\frac{0.35}{\frac{2}{3}x } =\frac{0.45}{x-10}$

Step 2: Solve for x

Cross-multiply: $0.35(x-10)=\frac{2}{3} x \cdot 0.45$
Distribute 0.35: $0.35x - 3.5=\frac{2}{3} x \cdot 0.45$
Multiply: $0.35x - 3.5=0.3x$
Isolate x term: $-3.5=-0.05x$
Isolate x: $70=x$
Rewrite: $x=70$

Step 3: Check

Plug in x to verify it's a solution.

Substitute: $\frac{0.35}{\frac{2}{3}(70) } =\frac{0.45}{70-10}$
Multiply: $\frac{0.35}{\frac{140}{3} } =\frac{0.45}{70-10}$
Subtract: $\frac{0.35}{\frac{140}{3} } =\frac{0.45}{60}$
Evaluate: $0.0075=0.0075$
