This is easy, hint, you multiply ;-;
8.6
Since there is one number before the decimal, we don't have to move the decimal
8.6 * 10^0
Answer 8.6 * 10^0
Lets Anna's age = A
Mr. Goldstein age = G
Mr. Goldstein is 4 times as old as his daughter Anna.
So G= 4A
In 4 years, he will be 3 times as old as Anna
we add 4 with Both their ages
G + 4 = three times of A + 4
G + 4= 3(A + 4)
We know G= 4A, replace it in above equation
4A + 4= 3(A + 4)
4A + 4= 3A + 12
Subtract 3A from both sides
A + 4 = 12
Subtract 4 from both sides
A = 8
So Anna's age = 8 years

Answer:
8x -24 = 9y
Step-by-step explanation:
We assume your equation is ...
2/3x -2 = 3/4y
__
Fractions can be eliminated by multiplying the equation by the least common denominator of the fractions.
LCM(3, 4) = 12
Multiplying the equation by 12 gives you ...
12(2/3x -2) = 12(3/4y)
8x -24 = 9y
