Answer:
Apply inverse law
a a⁻¹ = 1
The solution of the given linear equation is x = -6
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given equation -3 x-5=13
Adding '5' on both sides, we get
- 3 x - 5 + 5 = 13 + 5
- 3 x = 1 8
<u><em>step(ii):-</em></u>
apply inverse law
a a⁻¹ = 1
(- 3)(-3)⁻¹ x = 18 (-3)⁻¹
x = 18/-3 = -6
(or)
Dividing '-3' on both sides , we get

x =- 6
