Answer:
t = 3
Step-by-step explanation:
Given: 9t - (2t - 4) = 25
Distributive property: a(b + c) = ab + ac
1. Distribute '-' or '-1'
9t + -1(2t) + -1(-4) = 25
9t - 2t + 4 = 25
2. Combine like terms
7t + 4 = 25
3. Subtract 4 from both sides
7t + 4 - 4 = 25 - 4
7t = 21
4. Divide both sides by 7 to isolate the variable
7t ÷ 7 = 21 ÷ 7
t = 3
