how many solutions does the following equation have [tex] 8u+3(1/3u-6)=9u+2u+12[/tex]

Without even working out anything we can easily tell the answer is [tex]1[/tex] because the degree of the equation is one.

If you haven't learned this yet let me know and I will post the manual work.

Answer:

  1 solution

Step-by-step explanation:

When put in general form, the coefficient of u is non-zero, so there is 1 solution.

  0 = 9u +2u +12 -(8u +3(1/3u -6))

  0 = 11u +12 -8u -3(1/3u -6)

  0 = 3u +12 -u +18

  0 = 2u +30 . . . general form equation

  0 = u +15

  -15 = u . . . . . one solution
