mr jacob is 55 years old and tony is 7 years old. in how many years will mr. jacob be 4 times as old as tony?

solve

55+x = 4(7+x)

9years

To find out how many years it will take for Mr. Jacob to be four times as old as Tony, we can set up an equation.

Let's assume it will take x years for Mr. Jacob to be four times as old as Tony. Currently, Mr. Jacob is 55 years old, and Tony is 7 years old.

After x years, Mr. Jacob's age will be 55 + x, and Tony's age will be 7 + x.

According to the problem, Mr. Jacob will be four times as old as Tony. So, we can write the equation:

55 + x = 4(7 + x)

Now, we can solve the equation to find the value of x.

55 + x = 28 + 4x

Combining like terms, we get:

55 - 28 = 4x - x

27 = 3x

Dividing both sides by 3, we find:

x = 9

Therefore, it will take 9 years for Mr. Jacob to be four times as old as Tony.
