3. d-6 = - 10

4. m-14=-17

5. w-23=59

6. x-57 = - 15

7. x-31 = - 7

8. x + 51 = - 9

Answer: 3. d = - 4, 4. m = - 3, 5. w = 82, 6. x=42, 7. x=24, 8. x = - 60

Step-by-step explanation:

3. Step 1: Add 6 to both sides.

d-6+6=-10+6

d=-4

4. Step 1: Add 14 to both sides.

m-14+14=-17+14

m=-3

5. Step 1: Add 23 to both sides.

w-23+23=59 + 23

w = 82

Continue to repeat the step for the other ones. If there is a positive then subtract on both sides!
