Question

A number x is 4 less than three times another number y. If their sum is increased by 5, the result
is 25. Find both the numbers.
​

Answer 1

Answer:

Step-by-step explanation:

3y - 4 = x .......(1)

x + y + 5 = 25

So, X = 20 - y.....(2)

From (1) and (2)

3y - 4 = 20 - y

So , 4y = 24

Y = 6,

X = 14

Answer 2

Answer:

let the first number be x

let the second number be y

so according to the first condition

X = 3y - 4 -------- (1)

according to the second condition

X + y + 5 = 25

from (1)

3y - 4 + y + 5 = 25

4y + 1 = 25

4y = 25 - 1

4y = 24

y = 24/4

y = 6

putting value of y in eq. (1)

x = 3 (6) - 4

x = 18 - 4

X = 14

answer

so the first number = 14 = x

the second number = 6 = y
