Answer 2

Solving the Equation

To solve the given equation, we'll follow the order of operations (PEMDAS/BODMAS) to simplify the expression step by step.

1. Combine Like Terms - Combine like terms on both sides of the equation.

2. Isolate the Variable - Simplify the equation to isolate the variable on one side.

3. Solve for the Variable - Solve for the variable to find its value.

Let's start by combining like terms.

Step 1: Combine Like Terms

The given equation is: 20 - 3x + 2x - 45 + 4(13 - 3x) - 17 - 15x - (18 - 3x) - (4 + 2x) = 10

Combining like terms: 20 - 3x + 2x - 45 + 52 - 12x - 17 - 15x - 18 + 3x - 4 - 2x = 10 (20 - 45 + 52 - 17 - 18 - 4) + (-3x + 2x - 12x - 15x + 3x - 2x) = 10 (-12) + (-29x) = 10 -29x - 12 = 10

Step 2: Isolate the Variable

To isolate the variable, we'll add 12 to both sides of the equation: -29x = 10 + 12 -29x = 22

Step 3: Solve for the Variable

Finally, we'll solve for x by dividing both sides by -29: x = 22 / -29 x = -22/29

So, the solution to the given equation is: x = -22/29
