The answer is 21 here is the work
We can use the distributive property inside the brackets to get 18 - 2[x + x -5]. Next, we combine like terms to get 18 - 2[2x - 5]. Again, we use the distributive property to get 18 - 4x + 10, which when simplified even further, gives us 28 - 4x, or -4x + 28. Therefore, the answer to your query is -4x + 28. Hope my answer has come of assistance to you and have a great day!
If you would like to know what is 3 X minus 1/4 equals 6/7, you can calculate this using the following steps:
3 * X - 1/4 = 6/7
3 * X = 6/7 + 1/4
3 * X = 24/28 + 7/28
3 * X = 31/28 /3
X = 31/28 / 3
X = 31/28 * 1/3
X = 31/84
The correct result would be 31/84.
