Question

One number if five times another.Thier sum of is 90.What are these two number ?​

Answer 1

Answer:

Let numbers be x and y,

If number x is five times number y, then x=5y....eq.1

And if x+y =90....eq.2 then we have to solve the system.

X=5y...eq 1

X+y=90...eq.2

X+y =90...eq.2 substitute x from eq. 1

5y+y=90

6y=90

Y=90/6

Y=15.

Now back to eq.1 and find x

X=5y....eq.1

X=5×18

X=75

So the two numbers are 15 and 75

Answer 2

Answer:

15 and 75

Step-by-step explanation:

Let the first number be x

As given in question, five times of x+x=90

so,

5x+x=90

x=90/6

X=15
