Question

2+6y=3*+4

Answer 1

3*?

Answer 2

If the star is a typo:
2+6y = 7
6y = 5
y = 5/6

Answer 3

I helped with the last question like this. I believe the mistake is putting the plus sigh in front of the 4. The problem should read :
2 + 6y = 3 * 4
Is this correct @amiraguma . Is this the problem you are asking to be solved ?

Answer 4

if so...
2 + 6y = 3 * 4
2 + 6y = 12
6y = 12 - 2
6y = 10
y = 10/6
y = 5/3

check..
2 + 6(5/3) = 3 * 4
2 + 10 = 12
12 = 12 (correct)

Answer 5

the one I didn't at the fist one

Answer 6

is the * sign supposed to be in there ?

Answer 7

if it is supposed to be in there, you do not need the + sign in front of the 4. Now if it was -4, you would need the negative sign. If it just a number, like 3, and there is no sign, then it is assumed to be a positive number.
