Answer:
15-3(3a+b)+5-6b
15 - 9a - 3b + 5 - 6b
15 - 9a - 9b + 5
20 - 9a - 9b
Step-by-step explanation:
15-3(3a+b)+5-6b
Multiple everything inside of the parenthesis by -3.
15 - 9a - 3b + 5 - 6b
Get the variables together by doing -3b-6b
15 - 9a - 9b + 5
Add 5 to 15.
20 - 9a - 9b
Final answer: 20 - 9a - 9b

Answer:
Step-by-step explanation:
•Solve equation 1 for the variable x.
x = 3y - 27
•Plug this in for variable x in equation 2.
2×(3y-27) - 2y = 18
4y = 36
•Solve equation 2 for the variable y.
4y = 36
y = 9
•By now we know this much:
x = 3y-27
y = 9
•Use the y value to solve for x.
x = 3(9)-27 = 0
•Solution: {x,y} = {0,9}
