Answer

False

Work Step by Step

Type out the left side of the equation, replacing x with -170. -170 + 562 Hit enter, and the result should be 392. Now type out the right side of the equation, replacing x with -170. 3(-170) + 900 Hit enter, and the result should be 390. 390 is NOT equal to 392, therefore -170 is not the correct solution to the equation.
