1. 3x - 4y = -5
10x + y = -2
2. y + 6 = x
2x + 3y = 7
3. 2x + 5y = 23
12y - 4x = 20
4. 3y + 17x = -3
--7x + 4y - 8 = -12 + 2x
5. 2x + 3y - Z=-4
-X + 2y = 4
3y - 4z = -9

3-12. write each answer with a reasonable number of figures. find the absolute uncertainty and percent relative uncertainty for each answer. (a) [12.41 (±0.09) + 4.16 (±0.01)] x 7.068 2 (±0.000 4) =? (b) [3.26 (±0.10) x 8.47 (±0.05)] - 0.18 (±0.06) =? (c) 6.843 (±0.008) x 104 + [2.09 (±0.04)- 1.63 (±0.01)] =?
