Hi!
To solve this we have to get b on one side of the equation by itself.
Given the equation:
5 = 4/2(-1) + b
First, we divide 4 by 2, which is 2. Now we have:
5 = 2(-1) + b
Now we multiply 2 by -1, which is -2. Now we have:
5 = -2 + b
Now, we add 2 to both sides in order to cancel out the -2:
5 = -2 + b
+2 +2
7 = b
Hope this helps ! :D
