Question

Which expression is equivalent to 12x+3y−9x ?

Answer 1

`\text{You're going to need to combine like terms to get your answer}\\\\\text{Add or subtract the like terms:}\\12x+3y-9x\\\\\text{12x and -9x are like terms, so solve:}\\\\3x+3y\\\\\text{There are no more like terms, so your answer would be 3x + 3y}\\\\\boxed{3x+3y}`

Answer 2

The answer is 6x

You have to add 12 and 3 which is 15 then you have to do 15 minus 9 then it is 6 then you will put the x there because it had 2 x and 1y so 6x is the answer
