Select the solution to the following absolute value equation |x|=20. a. x=-20x or x=10 b. x=20x or x=-20 c. x=10 or x=20 d. x=9 or x=-18

x=20 or x=-20 is correct answer.

Step-by-step explanation:

Given the equation |x|=20.

we have to solve the absolute value equation.

An absolute value equation is an equation which contains an absolute value expression.

The equation  |x|=a has two solutions that are x = a and x = -a because both the numbers are at distance a from 0.

Hence, the solution of |x|=20 are x=20 or x=-20

∴  x=20 or x=-20 is correct answer.
