Question

Directions: Solve each equation. Check your solution(s) then indicate whether or not the solutions are extraneous. 1. (2x + 12 = 4x 2. 13x - 2) = 10 3. 3|x - 2) = 18 4. 3x - 2 = 18

Answer 1

[ 2x + 12 ] = 4x

12 = 4x - 2x

12 = 2x

6 = x

or

x = 6

the solution is not extraneous since 6 is included in the domain of the original equation.
