Answer:
y=9
Explanation:
Happy to help!
Lets break this down, shall we?
2(3y-6)=42
So we need to figure out what times 2 equals 42, correct?
42/2= 21
so this means that 3y-6=21
what minus 6 equals 21? lets turn that into an equation!
6+21=3y
whats 6+21? thats right, 27!
27=3y
now, we solve!
27/3= 9
y=9
Lets check out work!
2((3x9)-6)=42
3x9=27
2(27-6)=42
27-6=21
2x21=42
Hope this helps! ^^
