Begin inside the brackets always. Your first simplification will be to distribute the 3 into the parenthesis, resulting in this:
. We can simplify a bit more now inside the brackets like this:
. Now distribute the 3 to get 39x - 45 = 15x - 24. That's your answer. The third one out of the 4 you have there.

Step-by-step explanation:
Answer:
C. 70 = 10x
E. 15x = 105
Step-by-step explanation:
x = 7
Using method of elimination;
A. X + 7 = 17
Substituting the value of x;
7 + 7 ≠ 17 (Incorrect option)
B. 7 = 17 - x
Substituting the value of x;
7 ≠ 17 - 7 (Incorrect option)
C. 70 = 10x
Substituting the value of x;
70 = 10 * 7 (Correct option)
D. X/35 = 5
Substituting the value of x;
7 / 35 ≠ 5 (Incorrect option)
E. 15x = 105
Substituting the value of x;
15 * 7 = 105 (Correct option)
Answer:
If she gets 450 for 3 years plus 400 plus another 500 she would get exactly 2300.
Step-by-step explanation:
450 x 3 = 1350 + 550 = 1900 + 400 = 2300
(450 x 3) + 550 + 400 = 2300
