Answer 2

To solve the equation 5x - (3x + 9) - 2(5x - 3) = 5, follow these steps:

Step 1: Simplify the equation by applying the distributive property. Step 2: Combine like terms. Step 3: Isolate the variable (x) on one side of the equation.

Let's proceed with the solution:

Step 1: 5x - (3x + 9) - 2(5x - 3) = 5

Apply the distributive property: -2(5x - 3) = -10x + 6

Now the equation becomes: 5x - (3x + 9) - (-10x + 6) = 5

Step 2: Combine like terms in the equation: 5x - 3x - 9 + 10x - 6 = 5

Step 3: Combine further: (5x - 3x + 10x) - (9 + 6) = 5

Combine the x terms: 12x - 15 = 5

Step 4: Isolate x by moving the constant term to the other side of the equation: 12x = 5 + 15

12x = 20

Step 5: Finally, solve for x by dividing both sides by 12: x = 20 / 12

x = 5/3 or approximately 1.67

So, the solution to the equation is x = 5/3 or approximately x ≈ 1.67.
