Answer 1

Solve each:

1) 34x + 5 = −14 → 34x = −19 → x = −19/34.

2) (3/4)x + 5 = −1/4 → (3/4)x = −21/4 → x = −7.

3) −0.35x − 0.52 = 1.93 → −0.35x = 2.45 → x = −7.

4) −17x − 34 = 14 → −17x = 48 → x = −48/17.

5) −(1/7)x − 3/4 = 1/4 → −(1/7)x = 1 → x = −7.

6) 12x − 3 = 12 → 12x = 15 → x = 5/4.

7) (1/2)x − 3 = 1/2 → (1/2)x = 7/2 → x = 7.

Equations 2, 3 and 5 all have x = −7. The others have different solutions (−19/34, −48/17, 5/4, and 7).
