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]
