HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Solve: 7|x| = 42 –6 or 6 6 36 No solution x/ -5= -20 –100 or 100 –4 or 4 100 No solution

OpenStudy (dtan5457):

7x=42 7x=-42

OpenStudy (dtan5457):

there should be 2 solutions

OpenStudy (ajspeller):

Divide both side by 7. The remove the absolute value creating 2 equations. One side showing negative on one equation. And one side showing positive on the other equation.

OpenStudy (dtan5457):

x/-5=-20 take out the denominator. x=-5 times -20 x=?
