18-12+7
6 + 7
13
Write an equation.
Subtract first- the customer buys 12 black neon tetra fish which means subtraction
addition- the store clerk puts in 7 more black neon tetra fish which means your gonna add 7
Start by multiplying 3 times 3x to get 9x. Then multiply 3 times -6 to get -18
After that your equation is 18=9x-18
Then your going to add 18 to each side so your equation should be 36=9x
Then devide each side by 9 so the answer will be x=4
C loser that’s the correct number
7 to 9 I believe if you take 4 and 7 and make them more it schools be that
