Question 61299: 4a + 7 = 2a = 19
Answer by funmath(2933)   (Show Source):
You can put this solution on YOUR website! 4a + 7 = 2a = 19
You have a type-o. I'm going to change the second = into a +. Let me know if that's not what you meant and you still need help.
4a+7=2a+19
4a-2a+7=2a-2a+19
2a+7=19
2a+7-7=19-7
2a=12
2a/2=12/2
a=6
:
Check, if a=6, do both sides =?
4(6)+7=2(6)+19
24+7=12+19
31=31 Yes. We're right!!!
Happy Calculating!!!
