I think #1 is -1/2 but im not sure i dont know about the other answers
Y – 3x = 7
y -3x +3x = 7+3x
y = 7+3x
21 + 9x = 3y
21 + 9x = 3(7+3x)
21 + 9x = 21 + 9x
The answer is B.There are an infinite number of solutions.
I'm sorry but what was the question? Uploading the Image would be helpful.
A way we could find the answer is to subtract, so 175 - 120 equals 55, so hed $55 more to reach $175!
