Introduction

In mathematics, absolute value equations are a type of equation that involves the absolute value of a variable or expression. These equations can be solved using various techniques, including algebraic manipulation and graphical methods. In this article, we will focus on solving absolute value equations of the form ax+b=c|ax + b| = c, where aa, bb, and cc are constants.

Understanding Absolute Value

Before we dive into solving absolute value equations, it's essential to understand the concept of absolute value. The absolute value of a number is its distance from zero on the number line. For example, the absolute value of 3-3 is 33, and the absolute value of 55 is also 55. In mathematical notation, the absolute value of a number xx is denoted by x|x|.

Solving Absolute Value Equations

To solve an absolute value equation of the form ax+b=c|ax + b| = c, we need to consider two cases:

Case 1: ax+b=cax + b = c

In this case, we can simply solve for xx by isolating it on one side of the equation.

Case 2: ax+b=cax + b = -c

In this case, we can also solve for xx by isolating it on one side of the equation.

Solving the Given Equation

Now, let's apply the above techniques to solve the given equation: 11x+10=22|11x + 10| = 22.

Case 1: 11x+10=2211x + 10 = 22

To solve for xx, we need to isolate it on one side of the equation. We can do this by subtracting 1010 from both sides of the equation:

11x+1010=221011x + 10 - 10 = 22 - 10

This simplifies to:

11x=1211x = 12

Next, we can divide both sides of the equation by 1111 to solve for xx:

11x11=1211\frac{11x}{11} = \frac{12}{11}

This gives us:

x=1211x = \frac{12}{11}

Case 2: 11x+10=2211x + 10 = -22

To solve for xx, we need to isolate it on one side of the equation. We can do this by subtracting 1010 from both sides of the equation:

11x+1010=221011x + 10 - 10 = -22 - 10

This simplifies to:

11x=3211x = -32

Next, we can divide both sides of the equation by 1111 to solve for xx:

11x11=3211\frac{11x}{11} = \frac{-32}{11}

This gives us:

x=3211x = -\frac{32}{11}

Conclusion

In conclusion, we have solved the given absolute value equation 11x+10=22|11x + 10| = 22 using the two-case technique. We found that the solutions are x=1211x = \frac{12}{11} and x=3211x = -\frac{32}{11}.

Final Answer

The final answer is:

A. x=1211x = -\frac{12}{11} or x=3211x = \frac{32}{11}

This matches option A in the given problem statement.
