Solving equations with two absolute values
WebThe step in the above, where the absolute-value equation was restated in two forms, one with a "plus" and one with a "minus", gives us a handy way to simplify things: When we have isolated the absolute value and go to take … WebSolution. Already the absolute value expression is isolated, therefore assume the absolute symbols and solve. x + 2 = 7 → x + 2 = 7. Subtract 2 from both sides. x + 2 – 2 = 7 -2. x …
