Question

225+(−10t) = 50+15t
t= ?

Answer 1

To solve the equation \( 225 + (-10t) = 50 + 15t \), we can first simplify it:

\[
225 - 10t = 50 + 15t
\]

Next, we can move all terms involving \( t \) to one side and constant terms to the other side. Let's add \( 10t \) to both sides:

\[
225 = 50 + 15t + 10t
\]

This simplifies to:

\[
225 = 50 + 25t
\]

Now, subtract \( 50 \) from both sides:

\[
225 - 50 = 25t
\]

This simplifies to:

\[
175 = 25t
\]

Next, divide both sides by \( 25 \):

\[
t = \frac{175}{25} = 7
\]

Thus, the solution is:

\[
\boxed{7}
\]
