Question

solve z-6/z+3 =2/5

Answer 1

z=17/3

Answer 2

cross multiply

\[\frac{z - 6}{z+3}=\frac{2}{5}\]

then \[5(z-6) = 2(z+3)\]

all you need to do is expand , and collect like terms...

then solve for z

Answer 3

z= -24/7 ??

Answer 4

well you should have had

5z - 30 = 2z + 6

Answer 5

z=12

Answer 6

5z-2z=6+30
3z=36
z=36/3
z=12

Answer 7

lol... best answer to someone who got it wrong... good luck
