Part A: Connor is wrong, this is because the inequality 9x<27 means that 9x is LESS than 27. For example, if x was 17, it would mean 9 times 17 (153) which is WAAAY more than 27. Connor's statement is nonsense.
Part B: x could equal 2 or less. This is because anything over 2 will not fit with the inequality. (if x was 3 that would make it equal to 27 and that won't be right). 9 times 2 is 18 which is less than 27, so is 1 and so on :)
To equal the step 2, we would have to determine that 20 was our new denominator and multiply the first fraction by 5, the second by 4 and the 2 by 20.
multiplied by sides of the equation by 20
Answer:
x = 0
Step-by-step explanation:
5(x - 3) + 4(x + 3) = 3(x - 1)
5x - 15 + 4x + 12 = 3x - 3
5x + 4x + 12 - 15 = 3x - 3
9x - 3 = 3x - 3
9x = 3x - 3 + 3
9x = 3x
9x - 3x = 3x - 3x
6x = 0
6x ÷ 6 = 0 ÷ 6
x = 0
