Question

Solve the equation 3.5z-2.7z=-6

Answer 1

First you do 3.5z-2.7z= .8z then you divide .8 with -6, which gives you -7.5 so z= -7.5

Answer 2

Answer: The value of z is -0.75.

Step-by-step explanation:

The given equation is $3.5z-2.7z=-6$

In term to solve it to find z ,  we first simplify the left side.

By using distributive property :$ba+ca=(b+c)a$ , we get

$(3.5-2.7)z=-6\\\\\Rightarrow 0.8z=-6$

Now , Divide both sides by 0.8 , we will get

$z=\dfrac{-6}{0.8}=\dfrac{-60}{8}\\\\\Rightarrow\ z=-7.5$

Hence, the value of z is -0.75.
