Answer:
4.36
Step-by-step explanation:
14z-3-6-52 (Add all the numbers with the negative sign together)
= 14z-61 (Equation equals 0)
0 = 14z - 61 (Add 61 to zero)
0+61 = 14z ( Note :- the negative sign before 61 changes to +ve upon moving to the left hand side)
61 = 14z (Divide both sides by 14)
61/14 = 14/14
4.357 = z
z = 4.36
