Answer :
To solve these types of problems, write it out.
29+d=54
-29 -29 subtract 29 from both sides because you want the constants ---------- (numbers) on one side and the variable on the other
d= 25
DO THE SAME THING WITH ALL THE OTHER NUMBERS
you should get d= 25, -5, -4, -3
29+d=54
-29 -29 subtract 29 from both sides because you want the constants ---------- (numbers) on one side and the variable on the other
d= 25
DO THE SAME THING WITH ALL THE OTHER NUMBERS
you should get d= 25, -5, -4, -3
