Answer 1

25−4x=15−3x+10−x
25−4x=15−3x+10−x
−4x+25=−4x+25
−4x+25+4x=−4x+25+4x25=25
25−25=25−250=0

Answer 2

25-4x=15-3x+10-x is all real numbers. You must simply both sides of the equation. The problem is then -4x+25= -4x+25 which is the same. If this happens the answer is always all real numbers.
