Answer:
[tex]\boxed{\bold{x=6}}[/tex]
Step By Step Explanation:
Multiply Both Sides By 10
[tex]\bold{4.5x\cdot \:10-7\cdot \:10=20\cdot \:10}[/tex]
Simplify
[tex]\boxed{\bold{45x-70=200}}[/tex]
Add 70 To Both Sides
[tex]\bold{45x-70+70=200+70}[/tex]
Simplify
[tex]\bold{45x=270}[/tex]
Divide Both Sides By 45
[tex]\bold{\frac{45x}{45}=\frac{270}{45}}[/tex]
Simplify
[tex]\bold{x=6}[/tex]
