7y+-+44+=+12y+%2B+11 -------> working eqn
Combine similar terms:
-11-44=12y-7y
-55=5y-------> cross%28-55%2911%2Fcross%285%29=cross%285%29y%2Fcross%285%29
y=-11
In doubt? go back working eqn,
7%28-11%29-44=12%28-11%29%2B11
-77-44=-132%2B11
-121=-121
thank you,

7y-44=12y%2B11 Start with the given equation.


7y=12y%2B11%2B44 Add 44 to both sides.


7y-12y=11%2B44 Subtract 12y from both sides.


-5y=11%2B44 Combine like terms on the left side.


-5y=55 Combine like terms on the right side.


y=%2855%29%2F%28-5%29 Divide both sides by -5 to isolate y.


y=-11 Reduce.

Answer:

So the answer is y=-11
