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

$\bold{(45x)/(45)=(270)/(45)}$

Simplify

$\bold{x=6}$
