I dont understand hou to do this.... help
Don't be so lazy. TYPE just one of these questions in, lean from the answer, and do the others yourself.
You won't learn anything from copying all of other peoples answers.
Well, I'll solve one of them.
1. \(6x+4x-6=24+9x, 10x-6=24+9x, x=30\), so one solution.
Remember infinite solutions, 0=0, etc.
b) 25 - 4x = 15- 3x + 10 - x simplify
25 - 4x = 25 - 4x
Same expressions on both sides will give us infinite solutions for x
c) 4x + 8 = 2x + 7 + 2x - 20 simplify
4x + 8 = 4x - 13 subtract 4x from both sides
8 = -13 absurd answer means that no solutions exist.....
