Answer:

x=\frac{7}{8}

Step-by-step explanation:

10x-3-2x=4

First, collect and rearrange the like terms.

10x-3-2x=4

8x-3=4

8x=4+3

Then, solve the equation:

8x=4+3

8x=7

x=\frac{7}{8}

So, the answer is x=\frac{7}{8}. Hope my solution and explanation can help you. Thank you!

If you still cannot get the point, you can ask me anytime.

Answer:

x=7/8

Step-by-step explanation:

10x-3-2x=4

collect like term

8x-3=4

move constant to the right-hand side and change its sign

8x-3=4 into <u>8x=</u><u>4+3</u>

add up the number : 8x=4+3

8x=7 divide both sides of the equation by 8

<u>x = 7/8</u>
