Solve the inequality. So i have done this problem at least three times and I keep getting the same answer. But in the back of the book the correct answer for this problem is x<or equal to 5
This is what I did & my answer dosen't match the one in the back of the book:
9(x3)8(4x)> or equal to 2x
9x+2732+8 > or equal to 2x
9x+3 > or equal to 2x
added 9x to both sides
3> or equal to 7x
divided both sides by 7
My answer: x< or equal to 7/3
