Answer:
v=-5
Step-by-step explanation:
step one distribute -4 through the parentheses (so -4 times v and -4 times 7 which gives you (2v + 18 = 16 -4v -28)
step two calculate the difference (16 - 28=-12) (2v + 18 = -12 -4v)
step three move variables to the left hand side and change its sign (2v + 4v + 18=-12) move constant to the right hand side and change its sign (2v + 4v = -12 -18)
step four collect like terms ( add 2v +4v together to get 6v)(calculate the difference -12 -18 you add them because two negatives make a positive but keep the minus sign so you get -30)
step five divide both sides of the equation by 6 (6v + -30which gives you v=-5)
step six (v=-5) soultion
