Answer 3

To solve the equation (7 - 4x) - (3x + 2) = 12, follow these steps:

Step 1: Distribute the negative sign on the left side of the equation to both terms inside the parentheses:

7 - 4x - 3x - 2 = 12

Step 2: Combine like terms on the left side of the equation:

(7 - 2) - (4x + 3x) = 12 5 - 7x = 12

Step 3: Isolate the variable term by moving constants to the other side of the equation. To do this, add 7 to both sides of the equation:

5 - 7x + 7 = 12 + 7

This simplifies to:

5 - 7x = 19

Step 4: Now, subtract 5 from both sides to isolate the variable term:

5 - 5 - 7x = 19 - 5

This simplifies to:

-7x = 14

Step 5: Finally, divide both sides by -7 to solve for x:

(-7x) / (-7) = 14 / (-7)

x = -2

So, the solution to the equation is x = -2.
