The simplified form of this expression (- + ) + (4 − − 1) is 3 − 1.
Step-by-step explanation:First step for simplifying the equation is to put all the variables with same degree of power at one place:So, - + 4 + - - 1
= 3 − 1.We performed the addition and subtraction of the variable's coefficient with same order of power i.e (-1+4) +(1-1) -1.Finally the equation in the questions is reduced to simpler form as 3-1. The easy method to check is, assign any number to value of (say =2) in question. Now the option that gives the same value as question is our answer.
do 31÷13 and u will get ur answer
