Calculation Example

Let's work through some sample systems of equations:

Example 1: Solve 2x + 3y = 7, x - y = 1
Given System:
2x + 3y = 7
x - y = 1
Method:
Substitution Method
Step-by-Step Solution:
Step 1: From equation 2: x = y + 1
Step 2: Substitute into equation 1: 2(y + 1) + 3y = 7
Step 3: Simplify: 2y + 2 + 3y = 7
Step 4: 5y = 5, so y = 1
Step 5: x = 1 + 1 = 2
Answer: x = 2, y = 1
Example 2: Solve x + y = 5, 2x - y = 1
Given System:
x + y = 5
2x - y = 1
Method:
Elimination Method
Step-by-Step Solution:
Step 1: Add equations: (x + y) + (2x - y) = 5 + 1
Step 2: Simplify: 3x = 6
Step 3: x = 2
Step 4: Substitute: 2 + y = 5
Step 5: y = 3
Answer: x = 2, y = 3
Example 3: Solve using Matrix Method
Given System:
3x + 2y = 8
x - y = 1
Matrix Form:
[3 2] [x] = [8]
[1 -1] [y] = [1]
Step-by-Step Solution:
Step 1: Find determinant: det = 3(-1) - 2(1) = -5
Step 2: x = (8(-1) - 2(1)) / (-5) = 2
Step 3: y = (3(1) - 8(1)) / (-5) = 1
Answer: x = 2, y = 1
