Solve for z
-4z+1=bz+c

Steps to solve:

-4z + 1 = bz + c

~Subtract bz to both sides

−4z + 1 - bz = bz + c - bz

~Simplify

-bz - 4z + 1 = c

~Subtract 1 to both sides

-bz - 4z + 1 - 1 = c - 1

~Simplify

-bz - 4z = c - 1

~Factor out "z"

z(-b - 4) = c - 1

~Divide (-b - 4) to both sides

~Simplify

Best of Luck!

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
