Any value less than or equal to -2.09 is too low to be x. If you substitute a value less than or equal to -2.09 for x on the right side of the equation, it will result in a negative number (5x - 2.09), making it impossible for the left side (which is -7.2) to equal the right side. rephrase as a 7th grader
If the value of x is equal to or smaller than -2.09, it is considered too small. When you use a value that is smaller than -2.09 for x in the equation 5x - 2.09, you will get a negative number. This makes it impossible for the left side of the equation (which is -7.2) to be equal to the right side.
