Question
Use elimination to solve the system of equations. 6x−2y=16𝑥-2𝑦=1 10x−2y=5
Solution
The system of equations you provided seems to be incorrect. You have given three equations but only two variables (x and y). A correct system of equations should have the same number of equations as variables.
However, I can help you solve a system of two equations using elimination. Let's use the first two equations you provided:
- 6x - 2y = 16
- x - 2y = 1
Step 1: Align the equations
First, we align the equations so that like terms are vertically aligned:
6x - 2y = 16 x - 2y = 1
Step 2: Eliminate one variable
Next, we subtract the second equation from the first to eliminate y:
(6x - x) - (2y - 2y) = 16 - 1 5x = 15
Step 3: Solve for the remaining variable
Now we can solve for x by dividing both sides of the equation by 5:
5x / 5 = 15 / 5 x = 3
Step 4: Substitute x into one of the original equations
We can substitute x = 3 into the second equation:
3 - 2y = 1 -2y = 1 - 3 -2y = -2
Step 5: Solve for y
Finally, we solve for y by dividing both sides of the equation by -2:
-2y / -2 = -2 / -2 y = 1
So the solution to the system of equations is x = 3, y = 1.
