Solve the absolute value equation. |9x-3|=12

9 ×3 = 27

x = 5/3 OR x = -1

Step-by-step explanation: to solve this, we can rewrite the absolute value as two inequalities (one equal to the positive value, one equal to l the negative value) and solve each:

| 9x - 3 | = 12 becomes:

9x - 3 = 12

9x = 12 + 3

9x = 15

x = 15/9

x = 5/3 OR 1.66 as decimal

and now the other:

9x - 3 = - 12

9x = -12 + 3

9x = - 9

x = -9/9

x = -1

Because an equality is given, when we solve for x, there are technically just two possible values that would meet the conditions. Either 5/3 or - 1
