Answer:
[tex]\boxed{\bold{x=-3}}[/tex]
Step-by-step explanation:
Multiply both sides by 10
[tex]\bold{0.7x\cdot \:10-1.4\cdot \:10=-3.5\cdot \:10}[/tex]
Refine
[tex]\bold{7x-14=-35}[/tex]
Add 14 to both sides
[tex]\bold{7x-14+14=-35+14}[/tex]
Simplify
[tex]\bold{7x=-21}[/tex]
Divide both sides by 7
[tex]\bold{\frac{7x}{7}=\frac{-21}{7}}[/tex]
Simplify
[tex]\bold{x=-3}[/tex]
