3х - 5 (2x + 1) = 3 (3 - 2х)

Let's solve the equation step by step:

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

Step 1: Expand both sides

Left side: 3x - 5 * 2x - 5 * 1 = 3x - 10x - 5

Right side: 3 * 3 - 3 * 2x = 9 - 6x

So, the equation becomes: 3x - 10x - 5 = 9 - 6x

Step 2: Combine like terms on the left:

(3x - 10x) - 5 = 9 - 6x

-7x - 5 = 9 - 6x

Step 3: Get all x terms on one side and constants on the other:

Add 6x to both sides: -7x + 6x - 5 = 9 - 6x + 6x

• x - 5 = 9

Add 5 to both sides:

• x = 9 + 5

• x = 14

Multiply both sides by -1: x = -14

Final answer:

\[ \boxed{ x = -14 } \]
