Write the solution set of each equation.
Problem 1 :
│x - 5│ = 12
Problem 2 :
│x + 8│ = 6
Problem 3 :
│2a - 5│ = 7
Problem 4 :
│5b - 10│ = 25
Problem 5 :
│3x - 12│ = 9
Problem 6 :
│4y + 2│ = 14
Problem 7 :
│35 - 5x│ = 10
Problem 8 :
│-5a│+ 7 = 22
Problem 9 :
│8 + 2b│ - 3 = 9
Problem 10 :
│2x - 5│ + 2 = 13
Problem 11 :
│4x - 12│ + 8 = 0
Problem 12 :
│7 - x│ + 2 = 12
1) x = 17 (or) x = -7
2) x = -2 (or) x = -14
3) a = 6 (or) a = -1
4) b = 7 (or) b = -3
5) x = 7 (or) x = 1
6) y = 3 (or) y = -4
7) x = 5 (or) x = 9
8) a = -3 (or) a = 3
9) b = 2 (or) b = -10
10) x = 8 (or) x = -3
11) there is no solution.
12) x = -3 (or) x = 17
Solve each equation. Check for extraneous solution.
1) |3x – 4| = x Solution
2) |x + 24| = -7x Solution
3) |8x – 1| = 6x Solution
4) |4x + 5| = 2x + 4 Solution
5) |9 – 2x| = 10 + 3x Solution
6) |8 + 5x| = 7 - x Solution
7) |x – 1| = 5x + 10 Solution
8) |2z – 3| = 4z - 1 Solution
9) |3x + 5| = 5x + 2 Solution
10) |2y – 4| = 12 Solution
11) 3|4w – 1| - 5 = 10 Solution
12) |2x + 5| = 3x + 4 Solution
1) x = 2 and x = 1, No extraneous solution
2) x = -3 and x = 4, 4 is extraneous solution
3) x = 1/2 and x = 1/14, no extraneous solution.
4) x = -1/2 and x = -3/2, no extraneous solution.
5) x = -1/5 and x = -19, -19 is extraneous solution.
6) x = -1/6 and x = -15/4, no extraneous solution.
7) So, -3/2 is a solution and -11/4 is an extraneous solution.
8) So, -1 is a extraneous solution
9) So, -7/8 is the extraneous solution.
10) So, there is no extraneous solution.
11) So, there is no extraneous solution.
12) So, -9/5 is a extraneous solution.
