if you were to use the elimination method to solve the following method to solve the following system, choose the new systems of equations that would result after the variable z is eliminated in the second and third equations , then the first and second equations

5x+2y+z=-2
3x+4y+3z=2
-4x-3y-3z=1

anonymous · Answer

well you can take equation 2 and equation 3 add them which will give you a system of x and y only

anonymous · Answer

then you can mulitply equation 1 with 3 and either subtract equation 2 from  the first(now mulitiplied by3)
again you get system of x and y
take these two systems of x and y and solve for either one
