Question

Justify each step for 79 = 11x + 13

Answer 1

To justify each step for the equation 79 = 11x + 13, let's break it down:

Step 1: Start with the given equation: 79 = 11x + 13.

Step 2: Subtract 13 from both sides of the equation to isolate the term with the variable: 79 - 13 = 11x.

Step 3: Simplify the left side: 66 = 11x.

Step 4: Divide both sides of the equation by 11 to solve for x: 66/11 = x.

Step 5: Simplify the right side: 6 = x.

Therefore, the solution to the equation is x = 6. Each step is justified by maintaining equality between both sides of the equation.

Answer 2

Answer: x = 7

Explanation:

79 = 11x + 13

Step 1:- Subtract 15 from both sides

79 - 13 = 11x + 13 -13

66 = 11x

Divide both sides by 11,

x = 7

So, the required value of x will be 7
