Answer 2

To solve for the value of the unknown variable "а" in the equation "30а - а = 98.6", we need to simplify the equation by combining the like terms.

"30a - a" is equal to 29a, so the equation can be written as:

29a = 98.6

To solve for "a", we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 29:

a = 98.6 / 29

Using a calculator or long division, we can evaluate this expression and get:

a ≈ 3.4

Therefore, the value of "a" that satisfies the equation "30а - а = 98.6" is approximately 3.4.
