Answer:
The answer is x = 3.
(Hope this helps)
Step-by-step explanation:
3x + 2x = 5x
Now we can rewrite the equation as:
5x - 8 = 7
To solve for x, we want to isolate the variable on one side of the equation. To do this, we can add 8 to both sides:
5x - 8 + 8 = 7 + 8
5x = 15
Finally, we can solve for x by dividing both sides by 5:
5x/5 = 15/5
x = 3
Therefore, the solution to the equation is x = 3.
