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