Mr lee is 56 years old. His nephew, sam, is 4 years old. In how maby years’ time will mr lee be 5 times as old as his nephew
What is this????
L = 56
S = 4
L + x = 5 (S + x)
56 + x = 5 (4 + x) = 20 + 5 x
4 x = 36
x = 9
Wat
L= Mr Lee
S= Sam
Very confusing
To find out how many years it will take for Mr. Lee to be 5 times as old as his nephew, we can set up an equation.
Let's assume the number of years it will take is denoted by "x".
Mr. Lee's age after x years: 56 + x
Sam's age after x years: 4 + x
According to the problem, Mr. Lee will be 5 times as old as his nephew:
56 + x = 5 * (4 + x)
Now, we can solve this equation to find the value of x.
First, distribute the 5 to both terms inside the parentheses:
56 + x = 20 + 5x
Next, subtract x from both sides of the equation:
56 = 20 + 4x
Now, subtract 20 from both sides of the equation:
36 = 4x
Finally, divide both sides of the equation by 4 to solve for x:
x = 36 / 4
x = 9
Therefore, it will take 9 years for Mr. Lee to be 5 times as old as his nephew.
in x years:
Mr. Lee --- 56+x
Sam ---- 4 + x
56+x = 5(4+x)
solve for x
