Z= -1
It is a linear equation in the variable z.
6 + z/9 = 9 Therefore, z/9 = 3 3 x 9 = 27 Therefore, z = 27
If Z = 3, then (9 + 7Z) = [ 9 + 7(3) ] = 9 + 21 = 30
6z-4z-z = 6-7-4 z = -5
Z= -1
It is a singular matrix.

Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
3x + 2 = 82
x=4,y=9,z=5

-2
6 + z/9 = 9 Therefore, z/9 = 3 3 x 9 = 27 Therefore, z = 27
If Z = 3, then (9 + 7Z) = [ 9 + 7(3) ] = 9 + 21 = 30
y=5x+2 if y equals -4
