7y=7-12
add your like terms
7y=-5
isolate the y (divide by 7)
y= -5/7

First simplify the right side. 7 - 12 = -5. Then your equation is 7y = -5. Then you divide both sides by seven and your answer becomes y = -5/7.

7y=7-12
solve the problem to the right
7y=-5
move the 7 over with the opposite equation, this one being division
y= -5/7
you shouldn't need to solve any further but y = -5/7
if it was like 5x = 20+5 you would solve the right which is 25, then move the 5 over and divide 25 by 5 which x would equal 5.
or x/5=25 you would multiply 25 by the 5 where y = 125

The right side is 7-12 u get -5
therefore 7y = -5
just divide both sides by 7 u get
y= -5/7

7y= -5 then y= -5/7

First, do the easy part. 7-12= -5
So 7y = -5
Then you should know that if 7 x Y = -5, then -5 / 7 = Y
Then all you need is your calculator. -5 / 7 = -0.714285.
If -5 / 7 = -0.714285, then Y = -0.714285.

7y=7-12
7y=-5
y=-5/7
If y = -5/7..when we substitute -5/7 in place of y we get...
7(-5/7) = 7-12..or -5
7(-5/7) = -5
7 times X = -5
solve for X...-5/7 or .71435
proof =
7 (-.71435) = 7-12 or -5
Therefore y = -.71435

Do 7-12 first, then divide that answer by 7.

(7-12)/7= y
-5/7=y
-7.142 = y
