Solve the system: 2x + y = 6, -2x + 3y = 5
Question
Solve the system: 2x + y = 6, -2x + 3y = 5
Solution
Step 1: Write down the system of equations
2x + y = 6 -2x + 3y = 5
Step 2: Add the two equations together
2x + y + (-2x + 3y) = 6 + 5 0x + 4y = 11 4y = 11
Step 3: Solve for y
Divide both sides by 4 y = 11/4 y = 2.75
Step 4: Substitute y = 2.75 into the first equation
2x + 2.75 = 6 2x = 6 - 2.75 2x = 3.25
Step 5: Solve for x
Divide both sides by 2 x = 3.25/2 x = 1.625
So, the solution to the system of equations is x = 1.625 and y = 2.75.
