Answer:
Step-by-step explanation:
To solve for t, you have to isolate it on one side of the equation.
<h3>-17=-9+4t</h3>
<u>First, you have to switch sides.</u>
→ -9+4t=-17
<u>Add by 9 from both sides.</u>
<u>Then, you solve it.</u>
-17+9=-8
4t=-8
<u>Divide by 4 from both sides.</u>
<u>Solve.</u>
<u>Divide the numbers from left to right.</u>
-8/4=-2
- <u>Therefore, the correct answer is t=-2.</u>

Answer: 21a+17b
Step-by-step explanation: To get rid of the parenthese you must multiply or distribute 9 to all the numbers inside the parentheses.
9(a +b) + 4(3a + 2b)
9a+9b+12a+8b
Combine like terms
9a+9b+12a+8b
21a+17b
And we have our answer.
<em><u>21a+17b Hope this helps!</u></em>
