The Sum of 4 times one number and 3 times the second number is 65. The sum if the 2 numbers is 18. What are the numbers and equations you used

Verified Answer :

4x + 3y = 65
X + y = 18

When you use elimination, multiply the second equation by -3
4x + 3y = 65
-3X -3y = -54
X = 11


X+y = 18
11 + y = 18
Y = 7
