3 g + 5 = 17 ∣ − 5 3 g + 5 − 5 = 17 − 5 3 g = 12 / : 3 g = 3 12 g = 4
3g + 5 = 17
thus, 3g = 17 - 5 = 12
thus, 3g = 12
thus, g = 12/3 = 4.
Thus, g = 4.
To solve the equation 3 g + 5 = 17 , first subtract 5 from both sides to get 3 g = 12 . Then divide by 3 to find g = 4 . The solution checks out when substituted back into the original equation.
