Answer:
15/4 and 45/4
Step-by-step explanation:
Let x and y be the numbers
x = 3y
x+ y = 15
Substitute the first equation in to the second equation
3y+y = 15
4y = 15
y = 15/4
x = 3(15/4)
x = 45/4
The two numbers are 15/4 and 45/4
answer is 2
Step-by-step explanation:
2 times 2 equals 4
and 8 divided by 4 equals 2
Y= 12 - x
27 + 3( 12 - x ) = 2x
