Answer:
b = c/3 + 2/3
Explanation:
3b - 4/2 = c
the goal is to have b all by itself on one side of the equals sign.
start by moving the fraction over to where c is by adding.
3b = c + 4/2
adding -4/2 and +4/2 together makes it a 0 on the b side so there's no need to write anything in that space anymore.
Now 3b are next to each other which means they are multiplying. To move 3 we need to do the opposite (divide by 3 on both sides of the equal sign)
b = c/3 + 2/3
notice I divided both c and 4/2 by 3. 4/2 = 2 so I changed it to 2, then divided by 3
