Can anyone show me how to get the answer of 6-4a=13-3a?
Favorite Answer
subtract 6 both dies
-4a= 7-3a
add 3a to both sides
-a=7
divide by -1
a= -7
-4a+3a=13-6
-a=7
a= -7
6-4*(-7)=13-3*(-7)
6 + 28 = 13 + 21
34=34
Your result is correct
add 3a to both sides
6-a=13
subtract 6 from both sides
-a=7
a=(-7)
check your answer
6-4(-7)=13-3(-7)
6+28=13+21
34=34
Lets say that you grouped the other way
6-4a=13-3a
subtract 13 from both sides
-7-4a=-3a
add 4a to both sides
-7=a
check that answer
6-4(-7)=13-3(-7)
6+28=13+21
34=34
So, therefor a= (-7)
6-4a=13-3a
-13 +4a -13 +4a
-7=a
+3a to both sides
6-1a=13
subtract 6 from both sides
-1a=7
divide by -1 on both sides
a= -7
+4a +4a (add 4a to both sides)
——————–
6=13+1a
-13 -13 (subtract 13 from both sides)
—————–
-7 = 1a
— —– (divide by 1 on both sides)
1 1
-7 = a (I got the same answer as you!)
Hope this helps!
6-4a=13-3a
So next, get your numbers and the a’s on on side or the other, I chose a’s on right, numbers on left….
-7=1a (or a)
Simplifly, and you get -7=a
You did it right, great job, now do me proud and do the next ones, then if you need more help, keep asking here….ook??
6-13 = -7
-7-4a=3a 3a+4a=7a
-7=7a
a=-1
