Solve using elimination:
x + y = 5
2x - y = 4
tep 1: Identify the variable you want to solve for. Let's choose 'y'.
Step 2: Solve for 'y' in one equation. In Equation 1, we can solve for 'y': y = 5 - x.
Step 3: Substitute the expression for 'y' into the other equation (Equation 2): 2x - (5 - x) = 4.
Step 4: Simplify and solve: 2x - 5 + x = 4, 3x - 5 = 4, 3x = 9, and x = 3.
Step 5: Back-substitute the value of 'x' into one of the original equations to find 'y': 3 + y = 5 and y = 2.
Step 5: Back-substitute the value of 'x' into one of the original equations to find 'y': 3 + y = 5 and y = 2.
Therefore, the solution is x = 3 and y = 2.

Solve using elimination
9x + 6y = 3
4x - 6y = 20
9x + 6y = 3
4x - 6y = 20
-----------
13x = 23
x=23/13
3(23/13) + 2y = 1
69/13 + 2y = 1
2y = 1 - 69/13
2y = -56/13
y = -28/13
