3. d-6 = -10
4. m-14=-17
5. w-23=59
6. x-57= -15
7. x-31= -7
8. x + 51= -9

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!

answer: 0.64
