1. One-step addition & subtraction equations: fractions & decimals

2. Solution:- Get the variable on one side of the equation.
Example1 : = x
Solution:- Get the variable on one side of the equation.
We keep variable x on the right handside(RHS) and move constant to the
left handside(LHS)
6.2 – 2.2 =2.2 + x – 2.2
4.0 = x (ans)
By rule 1, 2.2 is added to the
variable x, so subtract 2.2 from
both sides of the equation
Example2 :- d = 0.75
Solution:- Get the variable on one side of the equation.
We keep variable d on the left handside(LHS) and move constant to the
right handside(RHS)
d – 0.5 = 0.75 – 0.5
d= (ans)
By rule 1, 0.5 is added to the
variable d, so subtract 0.5 from
both sides of the equation

3. from both sides of the equation
Example3 :-
Solution:- Get the variable on one side of the equation.
We keep variable g on the left handside(LHS) and move constant to the
right handside(RHS)
By rule 1, is added to the
variable g, so add
from both sides of the equation

4. from both sides of the equation
Example4 :-
Solution:- Get the variable on one side of the equation.
We keep variable g on the left handside(LHS) and move constant to the
right handside(RHS)
By rule 1, is added to the
variable c, so subtract
from both sides of the equation
