Hey guys,
There are some questions that have been giving me some trouble.
SOLVE:
6x+5=7+2x
Solve:
3(2z-5)=30
(i got z=7.5 for that one)
Solve the equation
1/2(x+3)-1/5(x-4)=5
Your not allowed trail and emprovement in this one
what did you get on this one? try to get all x's on one side and all constants on the other, then simplify
correctSolve:
3(2z-5)=30
(i got z=7.5 for that one)
$\displaystyle \frac 12 (x + 3) - \frac 15(x - 4) = 5$ .........multiply through by 10, we get:Solve the equation
1/2(x+3)-1/5(x-4)=5
Your not allowed trail and emprovement in this one
$\displaystyle 5(x + 3) - 2(x - 4) = 5$
now expand and conitnue
...or did you mean to type: $\displaystyle \frac 1{2(x + 3)} - \frac 1{5(x - 4)} = 5$. if so, you should use the proper parentheses. let me know what the question is. in this case, multiply through by $\displaystyle 10(x + 3)(x - 4)$
