Answer 2

1) x = 3,

2) s = 11,

3) z = 14,

4) y = 2,

5) q = 6,

6) n = 10,

7) r = 7,

8) m = 0,

9) p = 1,

10) a = 9.

Explanation:

1) Subtract 9 from both sides to isolate x, the result is 3.

2) Add one to both sides to isolate s, the result is 11.

3) Add 11 to both sides to isolate z, the result is 14.

4) Subtract 5 from both sides to isolate y, the result is 2.

5) Subtract 2 from both sides to isolate q, the result is 6.

6) Add 4 to both sides to isolate n, the result is 10.

7) Add 2 to both sides to isolate r, the result is 7.

8) Subtract 6 from both sides to isolate m, the result is 0.

9) Subtract 7 from both sides to isolate p, the result is 1.

10) Subtract 4 from both sides to isolate a, the result is 9.
