Question

Solve the equation and determine the value of t. t + 38 = 420 t =

Answer 1

Answer:

$t=382$

Step-by-step explanation:

$\mathrm{Subtract\:}38\mathrm{\:from\:both\:sides}$

$t+38-38=420-38$

$=382$

Answer 2

Answer:

$\displaystyle t = 382$

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

$\displaystyle t + 38 - 38 = 420 - 38 \\ \therefore \: t = 382$

let's verify it

$\displaystyle382 + 38\stackrel{?}{=}420$

simplify addition:

$\displaystyle420\stackrel{ \checkmark}{=}420$

hence, verified!
