Answer:
[tex] \displaystyle t = 382[/tex]
Step-by-step explanation:
we are given a equation
we want to figure out t
to do so
recall that
- addition equality property
- Substraction equality property
- multiplication equality property
- division equality property
therefore
if we substract 38 from both sides it won't affect the equality
so
[tex] \displaystyle t + 38 - 38 = 420 - 38 \\ \therefore \: t = 382[/tex]
let's verify it
[tex] \displaystyle382 + 38\stackrel{?}{=}420[/tex]
simplify addition:
[tex] \displaystyle420\stackrel{ \checkmark}{=}420[/tex]
hence, verified!
