systematic method for solving an equation class 6
Answers
Answer:
By rule of systematic method for addition, we can add the same number to both sides of the equation. In order to solve this equation, we need to get X by itself on LHS. Thus first let us add 5 on both sides of equation (1). Hence we get, 3x=12−(2).

Answer:
( i ) Always get same type of terms on one side for easy calculation
Ex: 2x + 3 = 3x - 5
= 2x - 3x = - 5 - 3
( ii ) If you want take LHS as RHS and RHS as LHS
Ex: 2x + 3 = 3x - 5
3 + 5 = 3x + 2x
3x + 2x = 3 + 5
( iii ) Positive number goes other side of equation as negative number
Ex : x + 3 = 0
x = -3
( iv ) Negative number goes other side of equation as positive number
Ex : x - 3 = 0
x = 3
( v ) Multiplicative number goes other side as denominator
x * 3 = 2
x = 2 / 3
Note : ( x * 3 ) + 2 = 5
In these type of cases, 3 can't go other side as denominator
But, ( x * 3 ) + ( 2 * 3 ) = 5 is equal to x + 2 = 5 / 3
( vi ) Denominator number goes other side as multiplicative number
Ex : x / 3 = 2
x = 2 * 3
Note : Same rule of ( v )
