Answer:

x=14 and y= 6

Step-by-step explanation:

let the first number be x

let the second number be y

so according to the first condition

X = 3y - 4

according to the second condition

X + y + 5 = 25

(3y - 4) + y + 5 = 25

4y + 1 = 25

4y = 25 - 1

4y = 24

y = 24/4

y = 6

putting value of y in equation

x = 3 (6) - 4

x = 18 - 4

X = 14

answer

so the first number = 14 = x

the second number = 6 = y

\bf{\underline{Question:-}}

  • A number x is 4 less than three times another number y.if their sum is increased by 5 the results is 25 find the both number.

\bf{\underline{Given:-}}

  • A number x is 4 less than three times another number y
  • their sum is increased by 5 the results is 25.

\bf{\underline{Find:-}}

  • find the both number ?

\bf{\underline{Solution:-}}

Let,

  • The number be X and Y

So

→ x = 3y - 4

→ x - 3y = - 4 -----equ(¡)

And,

→ x + y + 5 = 25

→ x+ y = 25 - 5

→ x + y = 20 ------equ(¡¡)

Solving both the equation

→ x - 3y = -4

\rm {\underline{_-x + _-y =_- 20 }}

→ - 4y = -24

→ 4y = 24

→ y = 24/4

→ y = 6

____________________

★ Substituting y = 6 in equ(¡)

→ x - 3y = -4

→ x - 3(6) = -4

→ x - 18 = -4

→ x = -4 + 18

→ x = 14

\bf{\underline{Hence:-}}

  • Both number are x = 14 & y = 6
