The correct answer would be B.
2 = coefficient
e = variable
- = operation
f = variable
2e = 2 × e
f subtracted from the product of two and e
With mental math, you can perform equations quickly and efficiently. They also help you to develop your own strategies and solve more complex math equations. Hope this helps;)
Please see attached image for the answer
Range: all real numbers
11x+(-2)because you would add like terms which is -1x and 12x which is 11 then u do 2-4 which is -2
