Best Answer

7X - 1 = 2X + 2

subtract 2X from each side

7X - 2X - 1 = 2X - 2X + 2

5X - 1 = 2

add 1 to each side

5X - 1 + 1 = 2 + 1

5X = 3

divide both sides integers by 5

(5/5)X = 3/5

X = 3/5

--------------check in original equation

7(3/5) - 1 = 2(3/5) + 2

21/5 - 1 = 6/5 + 2 (1 = 5/5 and 2 = 10/5 )

21/5 - 5/5 = 6/5 + 10/5

16/5 = 16/5
