What is the linear equation obtained by adding 7 to both sides of the equation 3x - 7 = 5x + 2 and then transposing 5x to left hand side of the equation?
-2x = 9
3x -7 = 5x + 2 is the given equation.
Result obtained after adding 7 to both sides is 3x - 7 + 7 = 5x + 2 + 7
3x = 5x + 9
Transposing 5x to left hand side
3x - 5x = 9
-2x = 9
