The statements given below are the steps that need to b
The statements given below are the steps that need to be followed in the method of substitution in random order. Arrange them in correct order to solve two equations.
1) Find the value of one variable, say y in terms of the x if x and y are the two variables.
2) Substitute the x we got from step 2 in either of the equation to get y.
3) Substitute this y in the second equation and it will be reduced to an equation in x, find x.

Right Answer is: B
SOLUTION
In substitution method, there are 3 steps
Step 1: Find the value of one variable, say y in terms of the x if x and y are the two variables
Step 2: substitute this y in the second equation and it will be reduced to an equation in x, find x
Step 3: substitute the x we got from step 2 in either of the equation to get y.
So these are the three steps involved in solving two equations by substitution method.
