Answer 2

The correct answer is "(a)x = 3" and "(b)x = 2".

Step-by-step explanation:

1...

$The \ given \ expression \ is:\\\\5x-3=2x+6\\\\On \ subtracting \ "2x" \ from \ both \ sides,we \ get\\\\5x-3-2x=2x+6-2x\\\\3x-3=6\\\\On \ adding \ "3" \ both \ sides,we \ get\\\\3x-3+3=6+3\\\\3x=9\\\\x=\frac{9}{3}\\\\x=3$

2...

$The \ given \ expression \ is:\\\\7-2x=x+1\\\\On \ subtracting \ "x" from \ both \ sides,we \ get\\\\7-2x-x=x+1-x\\\\7-3x=1\\\\On \ subtracting \ "7" \ from \ both \ sides,we \ get\\\\7-3x-7=1-7\\\\-3x=-6\\\\x=\frac{-6}{-3}\\\\x=2$
