That is an algebraic equation. If you are asking what the solution is for the above equation, it would be:
d = 7
8% of 50 = 4 50 + 4 = 54
50 + 50 = 100 3+5 = 8 100+8=108
Multiply by 10...
Do you mean: 11d +1 = 5d+49? If so: 11d+1 = 5d+49 11d-5d = 49-1 6d = 48 d = 8
It is the property that equals plus equals are equals.
-8 + 7x = x - 506x = -42x = -6
it is 28
89
244 plus 8 equals 252
40
Yes, -8 plus plus 3 equals -5. The "plus plus" is equivalent to a positive sign, so -8 plus (+3) equals -5.
