Answer:
Step-by-step explanation:
3x+4=5x-10
First, you have to combine your variables. By doing this you subtract 3x from both sides of the equation.
3x+4=5x-10
-3x -3x
4=2x-10
Next, you have to combine your whole numbers. In order to do so, you can subtract 2x and 4 from both sides so it would look like this:
4=2x-10
-2x -2x
-2x+4=10
-4 -4-
2x=-4-10
After that, you simplify -4-10, which is -14. Your equation should look like this:
-2x=-14
Finally, you need to isolate x. In order to do that, you need to divide -2 from both sides since you are multiplying -2 and x with the expression -2x.
-2x=-14
-2 -2
Your final answer is: x=7
