Jumoke is 11years older than amina. in 5 years time, jumoke will be twice as old as amina. Find amina present age

6 years old

Step-by-step explanation:

Suppose Amina's age is "a" and Jumoke's age is "j". We know that Jumoke is 11 years older than Amina, so we can say: j = a + 11

In 5 years' time, Jumoke will be twice as old as Amina then. In 5 years, Jumoke will be j + 5 years old, and Amina will be a + 5 years old. Since Jumoke will be twice as old then, the equation is: j + 5 = 2 * (a + 5)

We can substitute a + 11 in for j in the second equation:

(a + 11) + 5 = 2 * (a + 5) = 2a + 10

a + 16 = 2a + 10

a = 6

Thus, Amina's present age is 6 years old.

Hope this helps!

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
