x = 9.25

Explanation:

move the -3 to the other side of the = sign to make 71 + 3
so, 2x + 6x = 71 + 3
so, 8x = 74
now move the 8 to be divided in to 74 in other words, 74/8 (=9.25)

Therefore, X = 9.25

(reorder) 2x + 6x - 3 = 71
(add x's together) 8x - 3 = 71
(add 3 to both sides) 8x = 74
(divide both sides by 8) x = 9.25
