Add 2/7 to both sides
x = 6/7 + 2/7
simplify 6/7 + 2/7 to 8/7
Answer: x = 8/7 so 8/7 - 2/7 = 6/7 is true.

Answer:
5005
Step-by-step explanation:
70% of saving=$3850
To find the total: 3850*130% because 3850=1=100% and you still need to find the other 30% so you add another 30% which equals to 100%+30%=130%
3850*130%=5005
Let "what" and "what" be A and B
Put this in an algebraic equation
A * B = 21
A + B = -22
A must = -21 and B must = -1 , this is because two negatives multiply to make a positive
A + B = -22 , -21 +-1 = -22
An equivalent expression is (x+2)
