Question 745368: -7=3(t-5)-t
Answer by lenny460(1073)   (Show Source):
You can put this solution on YOUR website! -7 = 3(t-5) - t
3 * t = 3t
3 * -5 = -15
We now have:
-7 = 3t - 15 - t
Combine like terms:
3t - t = 2t
Therefore:
-7 = 2t - 15
Add 15 to each side of the equation.
-7 + 15 = 2t - 15 + 15
Combine like terms:
-7 + 15 = 8
-15 + 15 = 0
8 = 2t or
2t = 8
Divide each side by 2
2t/2 = 8/2
t = 4
Answer:
t = 4
