Answer = 18
If you mean x times 3 and y times 3, x= 8 and y = 2 so (8*3)-(2*3)=18
The answer is: -72.19634511
Answer:
3, 12
Step-by-step explanation:
"x" is the larger number,
"y" is the smaller number.
Given
x + y = 15
x / y = 4
manipulate the equations for the problem
x / y = 4
*y *y
x = 4y
solve the system of equations by the methord of substitution:
x + y =15
4y + y = 15
5y = 15
y = 3
Subsitute back into the equations given.
x = 4y
x = 12
