Answer:
x = -3
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
