Question

solve the equation using cramer's rule 2x+y -z = 3 x+y+z=1 x-2y-3z =4​

Answer 1

Answer:

Use the solution of the system below to find x-y:

4x-2y=11

3x-4y=-6

a 11.3

b 0.1

c -0.1

d -11.3

multiply the 1st equation by -2 and then add them to get rid of the y's [and hence find the x]

once you have the value of x sub it into either of the two equations to find y.

then just do x-y
