Question 234371: when two numbers are added together, the result is 45. twice the greater number is six more than five times the lesser number Answer by mando271(42) (Show Source):
You can put this solution on YOUR website! we'll let the numbers be x and y with x being the lesser
x+y=45
2y=5x+6
now we'll use substitution method to solve. I'll use the 1st equation to solve for y.
x+y=45
y=45-x
now plug this into the 2nd equation
2(45-x)=5x+6
90-2x=5x+6
-7x=-84
x=12
now plug this into our 1st solution to find y
y=45-12
y=33
so, x=12 and y=33
