 Question 114720: Solve. 3(x + 6) + 6x = 7x + 2Answer by ankor@dixie-net.com(15652)   (Show Source): You can put this solution on YOUR website!Here it is step-by-step : 3(x + 6) + 6x = 7x + 2 : Multiply what's inside the brackets: 3x + 18 + 6x = 7x + 2 : Add the x's on the left 9x + 18 = 7x + 2 : Subtract 18 from both sides 9x + 18 - 18 = 7x + 2 - 18 : 9x = 7x - 16 : Subtract 7x from both sides: 9x - 7x = 7x - 7x - 16 : 2x = -16 : 1x = -16/2; divide both sides by 2 : x = -8 : : Check our solution in the original equation substitute -8 for x: 3(x + 6) + 6x = 7x + 2 : 3(-8 + 6) + 6(-8) = 7(-8) + 2 : 3(-2) - 48 = -56 + 2 : -6 - 48 = -56 + 2 : -54 = -54, equality confirms our solution : Can you do these kind of equations now?
