1.7/8x=14
multiply each side by the reciprocal of 7%2F8, which is 8%2F7;
x=14%288%2F7%29
x=112%2F7
x=16
2.x%2F4+3x%2F5=17
find the LCD;
5x%2F20+12x%2F20=17
17x%2F20=17
multiply each side by 20;
17x=17(20)
17x=340
Divide each side by 17;
x=20
3. 5a-1 =-5 1/4
8
This problem, I'm not sure what you are asking, how the problem is suppose to be;
4. 5=a/6
multiply 6 to each side;
5(6)=a%2F6(6)
30=a
Hope this helps, if you can'nt figure out #3 e-mail it to me agian, you may have just made a type error.
