Answer: T=7

Step-by-step explanation:

0t−15−7.5t=6−0.5t

2 Simplify 10t-15-7.5t10t−15−7.5t to 2.5t-152.5t−15.

2.5t-15=6-0.5t2.5t−15=6−0.5t

3 Add 1515 to both sides.

2.5t=6-0.5t+152.5t=6−0.5t+15

4 Simplify 6-0.5t+156−0.5t+15 to -0.5t+21−0.5t+21.

2.5t=-0.5t+212.5t=−0.5t+21

5 Add 0.5t0.5t to both sides.

2.5t+0.5t=212.5t+0.5t=21

6 Simplify 2.5t+0.5t2.5t+0.5t to 3t3t.

3t=213t=21

7 Divide both sides by 33.

t=\frac{21}{3}t=

8 Simplify \frac{21}{3}

to 77.

t=7t=7
