Answer:

\boxed{\bold{x=6}}

Step By Step Explanation:

Multiply Both Sides By 10

\bold{4.5x\cdot \:10-7\cdot \:10=20\cdot \:10}

Simplify

\boxed{\bold{45x-70=200}}

Add 70 To Both Sides

\bold{45x-70+70=200+70}

Simplify

\bold{45x=270}

Divide Both Sides By 45

\bold{\frac{45x}{45}=\frac{270}{45}}

Simplify

\bold{x=6}
