8(1/4x+3/4)-3=17
Distribute
8/4x+24/4-3=17
Simplify the fractions
2x+6-3=17
Add 6, subtract 3 from both sides
2x=14
Divide both sides by 2
X=7
I hope I had interpreted the equation correctly if not tell me and I’ll resolve it :)
The correct answer is a.
All you do is change M+13=92 by subtracting 13 on both sides so that 13 cancels out on the left and 13 pages are subtracted from 92, and then you get your answer, which is m=79.
You can check your work by adding 13 and 79, and then you will know that that answer is correct
