Question

What is a=800 + 200t

Answer 1

Answer: t=
`(a-800)/(200)`

Explanation:

a=800 + 200t

Swap sides so that all variable terms are on the left-hand side.

800+200t=a

Subtract 800 from both sides.

200t=a−800

Divide both sides by 200.

`(200t)/(200)=(a-800)/(200)`

Dividing by 200 undoes the multiplication by 200.

`t=(a-800)/(200)`

Divide a−800 by 200.

`t=(a)/(200) - 4`
