Answer:

x = -3

Step-by-step explanation:

Combine multiplied terms into a single fraction

7x/10 - 1.4 = - 3.5

Add 1.4 to both sides of the equation

7x/10 - 1.4 + 1.4 = - 3.5 + 1.4

Simplify

7x/10 = - 3.5 + 1.4

7x/10 = - 2.1

Multiply all terms by the same value to eliminate fraction denominators.

10 × 7x/10 = 10(- 2.1)

Simplify

7x= 10(- 2.1)

7x = -21

-21 ÷ 7 = -3

x = -3
