The sum of two numbers is 27. The larger number is 6 more than twice the smaller number. Which system of equations can be used to find the two numbers

a. xy=27
y=6+x

b. x+y=27
y=6=2x

c. xy=27
y = 6+2x

d. x=y=27
y=6=x

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13
