Answer:
x=45
Step-by-step explanation:
add (3x-9)+30+24=180
subtract 30 and 24 from both sides
(3x-9) = 126
+9 on both sides
3x=135
divide by 3 on both sides
x=45

Hi, you don't provide us with the system here...
to figure out if 2,2 is a solution of the system, you have to plug the value of 2 in for both x and y in the system, and solve to see if it comes out or not...
If you provide the system I can definitely help you out more specifically!
1/2 because you can simplify 4/8 and do 4 divided by 4 and 8 divided by 4 which is 1/2
