The answer would be B. 2 times the X number minus 2 would be the Y for each.
The answer is the third one which would be x is less then or equal to 5
-16 + 5n = -7(-6 + 8n) + 3 Given
-16 + 5n = 42 - 56n + 3 Distribute
-16 + 5n = 45 - 56n Collect like terms
61n = 61 Add 56n to the left side and add 16 to the right side
n = 1 Divide 61 from both sides
The answer is n = 1. Remember that when you have a number beside two or more numbers in parentheses, you have to distribute, or multiply the number outside the parentheses by each number inside the parentheses.
Hope this helps!
Well think of it like this. lets say your teacher made you do this problem -48 - 10. I would just act like 48 is not an negative and add 10. After that I would put the negative back. So the answer would be -58. :P

➷ Find the multiplier:
1 + (3.4/100) = 1.034
Use this formula:
Final = original x multiplier^n
n is the number of years
Substitute the values in:
final = 6000 x 1.034^3
Solve:
final = 6633.0438
This can be rounded to the final answer of £6633.04
