Substitution Calculator

Substitution method is used to solve linear equations with two unknowns. In this method, we find the value for one unknown of one of the equation and substitute this value in any of the equation to find the new unknown value. Enter the equation A and B in the substitution calculator for solving the linear equations.
Steps Involved
Step 1: Solve 1 equation for y in terms of x
Step 2: Substitute 'y' equation in other equation to find x
Step 3: Substitute x value in y equation to find y.

Example:

Equation A : x + 2y = 2
Equation B : 2x + y = 4

Solution:

To solve for one unknown value, I have choosed second equation and 'y' variable.
Equation B : 2x + y = 4
Solving for 'y' in terms of 'x', we have
y = 4 - 2x
Now, substituting 'y' equation in Equation A
x + 2y = 2
x + 2(4-2x) = 2
x + 8 - 4x = 2
x - 4x = 2 - 8
-3x = -6
x = -6 / -3
x = 2
Substituting the value for x in y equation, we have
y = 4 - 2x
y = 4 - 2x2
y = 0

Substitution method calculator is an easy to use tool for solving linear equations with two unknowns.
