Question

Help plz tell me what to write

Answer 1

Hello @Smithalmuwahidy,

How are you doing? Lets work each equation by their-self. Lets start with the first equation:
`a-5.1=1.7`

You would need to move all terms not including "a" to the right side of the equation. You also need to combine like terms like shown below:

`a-5.1=1.7 a(-5.1+ 5.1)=(1.7+ 5.1) a=6.8`
Your answer is a=6.8 :)

Moving on to the second equation:

`-31=z+(-17)`
You would do the same as the last equation, to get z=-14.

I hope this helped you, and if you need further help contact me.

Thank you,
Darian D.

Answer 2

a - 5.1 = 1.7
a - 5.1 + 5.1 = 1.7 + 5.1
a = 6.8




-31 = z + (-17)
-31 + 17 = z + (-17) + 17
-14 = z
