Step-by-step explanation: Let the no. be X and Y first equation, X -Y = 3 Second equation, 2X + 3Y = 19 from equation no. 1 , X= 3+Y Put this value of X in equation no. 2 2(3+Y) + 3Y = 19 6+2Y + 3Y = 19 6+ 5Y = 19 5Y= 19-6 5Y = 13 Y= 13÷5 Y = 2.6 Put this value of Y in equation no. 1 X-Y= 3 X – 13/5 = 3 X = 13/5+3 taking lcm X= 28/5 Reply
Answer: 2 and 5 are the two numbers. Step-by-step explanation: Question : Two numbers differ by 3. The sum of twice the smaller number and thrice the greater number is 19. Find the number. Solution : Two numbers differ be 3 : Let the first number be x, then the second number will be x + 3. Sum of twice the smaller number and thrice the greater number is 19 : 2(x) + 3(x + 3) = 19 2x + 3x + 9 = 19 5x + 9 = 19 5x = 19 – 9 5x = 10 x = 2 The two numbers are : The smaller number (x) = 2 The greater number (x + 3) = 2 + 3 = 5 Reply
Step-by-step explanation:
Let the no. be X and Y
first equation,
X -Y = 3
Second equation,
2X + 3Y = 19
from equation no. 1 ,
X= 3+Y
Put this value of X in equation no. 2
2(3+Y) + 3Y = 19
6+2Y + 3Y = 19
6+ 5Y = 19
5Y= 19-6
5Y = 13
Y= 13÷5
Y = 2.6
Put this value of Y in equation no. 1
X-Y= 3
X – 13/5 = 3
X = 13/5+3
taking lcm
X= 28/5
Answer:
2 and 5 are the two numbers.
Step-by-step explanation:
Question :
Solution :
Two numbers differ be 3 :
Let the first number be x, then the second number will be x + 3.
Sum of twice the smaller number and thrice the greater number is 19 :
2(x) + 3(x + 3) = 19
2x + 3x + 9 = 19
5x + 9 = 19
5x = 19 – 9
5x = 10
x = 2
The two numbers are :
The smaller number (x) = 2
The greater number (x + 3) = 2 + 3 = 5
