To find: the numbers according to the given system of equation.

Answer to Problem 42PPS
Explanation of Solution
Given:
Three times the difference of four times a number and three times a second number is 117.
And the four times the sum of six times the second number and eight times the first number is 72.
Calculation:
Let the first number be x and second number be y .
According to the question,
Now, solve the both equation so that to get the numbers
Using elimination method to equate:
Multiply equation (1) by 2 to get
Now, subtract the equation
Now, substitutes the value of y in 2nd equation, then:
Hence, numbers according to the given system of equation is
