Answer 2

Let's solve the given equation step by step:

5x + 2(3 - x) = 3(5 - 2x) - 1

First, let's simplify the expressions inside the parentheses:

5x + 6 - 2x = 15 - 6x - 1

Combine like terms on both sides of the equation:

3x + 6 = 14 - 6x

Add 6x to both sides:

3x + 6x + 6 = 14 - 6x + 6x

Combine like terms again:

9x + 6 = 14

Subtract 6 from both sides:

9x + 6 - 6 = 14 - 6

9x = 8

Finally, divide both sides by 9 to solve for x:

(9x)/9 = 8/9

x = 8/9

Therefore, the solution to the equation is x = 8/9.
