Answer:
Step-by-step explanation:
x + 3y = 24
5x + 3y = 36
Like you said, BUT
if you were to subtract the equations
x - 5x = -4x
Then the 3ys would cancel out. Leaving:
-4x = 12
x would equal -3
Answer:
First number = 3.
The other number = 7.
Step-by-step explanation:
I am assuming you mean 'one number added to three times another number is 24'. Let the 2 numbers be x and y.
We have the following system of equations:
x + 3y = 24
5x + 3y = 36
Subtracting the 2 equations ( the second minus the first):
4x = 12
x = 3
Substituting x = 3 in the first equation:
3 + 3y = 24
3y = 24 - 3
3y = 21
y = 7.
