The sum of two integers is 704 and the larger number is 11 more than 8 times the smaller number. Find the two integers.
Let us say that the two integers are X and Y.
Let X be greater than Y.
Given that the sum of the two integers is 704.
Therefore the first equation would be
X+Y=704—–> Equation 1
We are also given that the larger number is 11 more than 8 times the smaller number.
Hence the equation corresponding to this sentence would be
X=8X +11—–>Equation 2
X+Y=704—> Equation 1
X=8Y +11—>Equation 2
From Equation 1, Y=704-X
Substituting the value of Y =704-x in the equation 2.
X= 8( 704-X)+11
Therefore the value of y = 704-X=704-627
We can cross-check the answers we got.
Let us plug the values of X and Y in the first equations to check whether they hold good.
Therefore the X and Y values we found work good for the equation1.
Let us plug the values of X and Y in the second equations
Therefore the X and Y values we found work good for equation 2.
