Question

Help me with this equation please?

Answer 1

\[\frac{ x }{ x+3 } + \frac{ 2 }{ 5 } = 0\]

Answer 2

step one is to separate the unknowns and the the constants. SO subtract 2/5 from both sides.

Answer 3

\[\frac{ z }{ z+3} + \frac{ 2 }{5} -\frac{ 2 }{5} = 0 - \frac{ 2 }{5} \]

Answer 4

\[\frac{ z }{ z+3} = - \frac{ 2 }{5} \]

Answer 5

cross multiply the denominators now\[5 \times z = -2 \times (z+3)\]

Answer 6

can you take it from here?

Answer 7

So my answer is \[-\frac{ 6 }{ 7 }?\]

Answer 8

correct :)
z= -6/7

Answer 9

Thanks soooooo much :)
