Let's solve the equation [tex]\( 315 = 216 + t \)[/tex].
1. Start with the original equation:
[tex]\[
315 = 216 + t
\][/tex]
2. To isolate [tex]\( t \)[/tex], we need to get rid of the [tex]\( 216 \)[/tex] on the right-hand side. To do so, subtract [tex]\( 216 \)[/tex] from both sides of the equation:
[tex]\[
315 - 216 = 216 + t - 216
\][/tex]
3. Simplify both sides:
[tex]\[
315 - 216 = t
\][/tex]
4. Performing the subtraction gives:
[tex]\[
99 = t
\][/tex]
Thus, [tex]\( t = 99 \)[/tex].
So the solution to the equation [tex]\( 315 = 216 + t \)[/tex] is [tex]\( t = 99 \)[/tex].
