Question

What is 4f+10f-f=

What is (7p+4)-p+2)=

What is 5-3j+7+9j+2+

Answer 1

13f

6p+6

14+6j (provided the last symbol is = and not +)

Explanation:

the thought is to add like terms

the coefficients the have unknowns (f, p and j) are added together then the constants are added together taking into account the signs

(4+10-1)f = 13f

likewise with the others
