Answer 3

Let's solve the equations one by one:

1. 2 + b = 30 Subtract 2 from both sides: b = 30 - 2 b = 28

2. 70 - c = 14 Subtract 70 from both sides: -c = 14 - 70 -c = -56 Multiply both sides by -1 to solve for c: c = 56

3. 34 - x = 19 Subtract 34 from both sides: -x = 19 - 34 -x = -15 Multiply both sides by -1 to solve for x: x = 15

4. 5 * m = 55 Divide both sides by 5: m = 55 / 5 m = 11

5. k : 16 = 4 Multiply both sides by 16 to isolate k: k = 4 * 16 k = 64

6. а * 40 = 120 Divide both sides by 40: а = 120 / 40 а = 3

7. 42 : x = 14 Multiply both sides by x to isolate 42: 42 = 14 * x Divide both sides by 14 to solve for x: x = 42 / 14 x = 3

8. 60 : d = 5 Multiply both sides by d to isolate 60: 60 = 5 * d Divide both sides by 5 to solve for d: d = 60 / 5 d = 12

9. n + 320 = 410 Subtract 320 from both sides: n = 410 - 320 n = 90

So the solutions to the given equations are: b = 28 c = 56 x = 15 m = 11 k = 64 а = 3 x = 3 d = 12 n = 90
