Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A specific value (or set of values) that makes an equation or inequality true when substituted in for the variable.
The answer to 'what value of x makes this equation true?' — found by solving, confirmed by checking.
Example 1
easyIs x = 3 a solution of x^2 - 9 = 0?
Example 2
mediumFind all solutions of |x| = 5.
Example 3
easyWhich values are solutions of x^2 = 16: x = 4, x = -4, x = 8?
Example 4
mediumDoes the equation x + 1 = x + 2 have any solutions?
