3x+4=5メー10
How to slove

Answer 1

Yu have to multiply 3 with the 5 with that answer

Answer 2

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
