Question

(-10)*(-10)= 100. but -10^2 = -100​

Answer 1

Answer:

Step-by-step explanation:

In equation always there will be two sides wrt equal sign (=), left hand side (LHS) and right hand side (RHS). Here in LHS two terms are there (10x) and (-10).

10x - 10 = 100

First of all we will just transfer without x term to RHS. Remember when we transfer the term from one side to another the sign of that term will be changed to opposite sign.

10x = 100 + 10

It was -10 in LHS and now it is +10 in RHS

10x = 110

Again in LHS 10 is multiplied with x so we will transfer it from LHS to RHS by changing the sign from multiplication to division.

x = 110/10

x = 11
