Let's say for example I have;
7x + 8 = 71 I don't have a problem solving this, I can do it as follows;
7x + 8 - 8 = 71 - 8
7x = 63
7x/7 = 63/7
x = 9
The above was done, as you can see by using the addition/subtraction rule and then the division rule.
However, the follwing equation stumps me;
45 - 5x = 50
Can someone enlighten me?
