Multiply you first equation by 2 to get 4x + 10y = 22
Now the x terms can be eliminated and cancelled out using elimination.
4x + 10y = 22
4x + 3y = 1
To eliminate you need to "subtract", so you need to multiply one of the equations by -1.
4x + 10y = 22
-4x -3y = -1
------------------
0 + 7y = 21
y = 3
Now plug 3 into either one of the equations to get x.
Answer:
Omg my oth acc is gone
Step-by-step explanation:
X=6
16 plus 2 is 18 and divided by 3 is 6
Looks like the system is
We can eliminate by taking
so that , and
Substitute into this last equation and solve for :
Then
Plug these values into any one of the original equation to solve for :
Hence the solution is x = 4, y = -3, and z = 2.
