Answer 3

Equation 1: 2(11x - 5) - 17x = 55

To solve this equation, we will follow the steps of simplifying and isolating the variable.

Step 1: Distribute the 2 to the terms inside the parentheses: 2(11x - 5) - 17x = 55 22x - 10 - 17x = 55

Step 2: Combine like terms on the left side of the equation: 22x - 17x - 10 = 55 5x - 10 = 55

Step 3: Add 10 to both sides of the equation to isolate the variable term: 5x - 10 + 10 = 55 + 10 5x = 65

Step 4: Divide both sides of the equation by 5 to solve for x: 5x/5 = 65/5 x = 13

Therefore, the solution to equation 1 is x = 13.

Equation 2: 5(8x + 3) - 12 = 83

Let's solve this equation using the same steps as before.

Step 1: Distribute the 5 to the terms inside the parentheses: 5(8x + 3) - 12 = 83 40x + 15 - 12 = 83

Step 2: Combine like terms on the left side of the equation: 40x + 15 - 12 = 83 40x + 3 = 83

Step 3: Subtract 3 from both sides of the equation to isolate the variable term: 40x + 3 - 3 = 83 - 3 40x = 80

Step 4: Divide both sides of the equation by 40 to solve for x: 40x/40 = 80/40 x = 2

Therefore, the solution to equation 2 is x = 2.

In summary: Equation 1: x = 13 Equation 2: x = 2
