A system of equations is a set of equations which are collectively satisfied by one solution of...Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. 2x+y-z=22x+y−z=2. , x+3y+2z=1x+3y+2z=1. , x+y+z=2x+y+z=2.Solve the system by the elimination method. Check your work. 2a + 3b = 6 5a + 2b - 4 = 0 Make sure there are NO SPACES in your answer. 3x + 2y = A 5x + y = B Eliminating the variable y from the system of equations results in -7x =.

I'm assuming you might have a typo in your 2nd equation (the remaining x is a z?)

(equation 1) -2x + 2y + 3z = 0

(equation 2) -2x - y + z = -3

(equation 3) 2x + 3y + 3z = 5

The trick is to use pairs to be able to produce two equations with simplest two variables (having eradicated the third one)

Here, we can upload in combination 1 + 3 and a pair of + 3

Adding in combination equations 1 and three (left + left = proper + right):

0x + 5y + 6z = 5

Adding in combination equations 2 and 3:

0x + 2y + 4z = 2

We do away with 0x (it has been eliminated) and we're left with this system:

5y + 6z = 5

2y + 4z = 2

We multiply the most sensible equation by 2, and the backside one by -5

10y + 12z = 10

-10y - 20z = -10

We add them together (which gets rid of y)

0y - 8z = 0

due to this fact z=0

Once we now have a price for z, we paintings backwards, finding a worth for y, the usage of, for example:

10y + 12z = 10

which is now

10y + 12(0) = 10

10 y = 10

y = 1

and back to any one in every of the unique equations (the use of z=0 and y=1) to seek out x.

---

Once you could have found values for x, y and z, ALWAYS return to the authentic equations to verify those values paintings for ALL the equations.

If they don't, get started over.
