Question

If you were to use the elimination method to solve the following system, choose the new system of equations that would result after the variable z is eliminated in the first and second equations, then the second and third equations.

3x - 5y + 2z = 7
4x + 9y - z = 2
x - 3y + 3z = 7

Answer 1

To eliminate z from the first two equations, multiply the second equation by 2 and add it to the first.
To eliminate z from the last two equations, multiply the second equation by 3 and add it to the third.
What you will be left with are two equations and two unknowns.

Answer 2

O.o

Answer 3

3x - 5y + 2z = 7
4x + 9y - z = 2
x - 3y + 3z = 7
--------------
12x+135y+1z= ranga it would be like this and what about the once of the = u multiple too or just +

Answer 4

7+2+7=16 or 7*2*7=98

Answer 5

ranga
