Answer:
x = 27
Explanation:
The first thing we want to do in this algebraic expression is to remove the known number from the side with the largest x value. In our case, it's 40, and the way we remove it is by adding or subtracting from both sides, since our's is negative we'll add it to both sides.
- 40 + 3x = x + 14
+40 +40
3x = x + 54
Now that we have put the two common numbers together were going to add or subtract the smaller x value on both sides, here it's x.
3x = x + 54
-x -x
2x = 54
This is the last step in finding our solution, here we want to divide both numbers by the number next to x, which is 2.
2x / 2 = x
54 / 2 = 27
Now that we have divided both numbers we know that our answer is
x = 27
Hope this helps, good luck with the rest of your day :)
