We know that the absolute value of a positive number is itself, and the absolute value of a negative number is its opposite, while the absolute value of 0 is 0. In other words,|x|={x,x≥0,x,x<0.#Consequently,#|x|=|x|,|xy|=|x||y|;If|x+y|=a,thena≥0;If|x+y|=|xy|...
6.3 – Equations and Inequalities with Absolute ValueLearning Objectives (6.3.1) – Solve equations containing absolute values Equations with one absolute value Equations with two absolute values Recognize when a linear equation that contains absolute value does not have a solution (6.3.2) ...
Absolute Values On One Side Of The Equation When solving an equation with absolute values, it is necessary to split the equation into two equations, one resulting in a positive value and the other resulting in a negative value. We can then solve the two equations to obtain two possible solut...

I do not see how the two equations in each example are related, what should I do with them? (the l's are absolute value brackets): a) Let g(x) = 3x - 3 + l x+5 l. Find all values of a which satisfy the equation: g(a) = 2a +8 b) Let h(x) = l x l - 3x + 4...
Solving inequalities containing absolute value and graphing Tosolve an inequality containing absolute value, begin with the same steps as for solving equations with absolute value. When creating the comparisons to both the + and – of the other side of the inequality, reverse the direct...
Absolute value equations|a| = 5.What values could a have?a could be either 5 or −5. For if we replace a with either of those, the statement -- the equation -- will be true.And so any equation that looks like this --|a| = b...
Rules Before Performing Operations with Absolute Value Before performing operations with absolute values, remember to perform the operation inside of the absolute value symbols first (if possible). Then perform additional operations according to the order of operations model (PEMDAS/GEMDAS). Absolute ...
