Answer:
21.6
Step-by-step explanation:
130/6
Answer:
Reduce the greatest common factor on both sides of the equation: (2x+y=12
(x-3y=27
Rearrange like terms to the same side of the equation: (2x+y= 12
(x=27+3y
Substitute into one of the equations: 2(27+3y)+y=12
Apply Multiplicative Distribution Law: 54+6y +y=12
Rearrange unknown terms to the left side of the equation: 6y+y=12-54
Combine like terms: 7y=12-54
Calculate the sum or difference: 7y=-42
Divide both sides of the equation by the coefficient of variable: y= -42÷7
Calculate the product or quotient: y= -6
Substitute into one of the equations: x=27+3×( -6)
Remove the parentheses: x=27-3×6
Calculate the product or quotient: x=27-18
Calculate the sum or difference: x=9
The solution of the system is: x=9
y=-6
Answer:
x=9
y=-6
there is no way thats a real question the answer is "a number"
thanks for the points
The no. is 8.
