11. The sum of two numbers is 13. Two times the first number minus three times the second number is 1. If you let x stand for the first number and y for the second number, what are the two numbers?
Answers
Answer:
Step-by-step explanation:
If you let x stand for the first number and y for the second number, then we were given: x + y = 13 2x - 3y = 1 Solve the equation we get x = 8, y = 5 The sum of two numbers is 13. Two times the first number minus three times the second number is 1. If you let x stand for the first number and y for the second number, the two numbers are: A. x = 8, y = 5
Let the two no.s be x and y
According to the question :-
And it is also stated the two times the first no. (2x) minus ( - ) three times the second no. (3y) is equivalent to 1
Now, multiply the entire 1st equation with 2 in order to get the identical coefficients of "x" By doing this we can easily eliminate the x by subtracting the equations and find the value of y
Let's perform this :-
Multiply the 1st equation with 2
Now, Subtract these two equations to find the value of y
Now, substitute the value of y in any of the equations to find x. For now, let's substitute it in equation (1)
