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

<u>-3x     -3x</u>

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

<u>-2x   -2x</u>

-2x+4=10

<u>-4        -4</u>-

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.

<u>-2x</u>=<u>-14</u>

-2    -2

Your final answer is:      x=7
