Answer:
t = -11
Step-by-step explanation:
Solve for t:
-3 t - 8 = 25
Add 8 to both sides:
(8 - 8) - 3 t = 8 + 25
8 - 8 = 0:
-3 t = 25 + 8
25 + 8 = 33:
-3 t = 33
Divide both sides of -3 t = 33 by -3:
(-3 t)/(-3) = 33/(-3)
(-3)/(-3) = 1:
t = 33/(-3)
The gcd of 33 and -3 is 3, so 33/(-3) = (3×11)/(3 (-1)) = 3/3×11/(-1) = 11/(-1):
t = 11/(-1)
Multiply numerator and denominator of 11/(-1) by -1:
Answer: t = -11
Explanation
- Given the equation.
[tex] - 3t + ( - 8) = 25[/tex]
- Distribute the plus/positive in the negative. Remember that plus × minus = minus.
[tex] - 3t - 8 = 25[/tex]
- Solve for t-term by making t as the subject of equation.
[tex] - 3t = 25 + 8 \\ - 3t = 33 \\ t = \frac{33}{ - 3} \longrightarrow \frac{ \cancel{33}}{ \cancel{ - 3} } = \frac{11}{ - 1} \\ t = - 11[/tex]
- Answer Check by substituting the value of t in the equation.
[tex] - 3( - 11) + ( - 8) = 25 [/tex]
Distributing or multiplying both negative, we would get positive.
[tex]33 - 8 = 25 \\ 25 = 25 \: \: \purple{ \checkmark}[/tex]
The equation is true for t = -11. Hence the answer is t = -11.
