I need help on a math question! Please help..
the equation is x/5 + x/a = c [ You have to solve for x ]
The correct answer is suppose to be 5ac/a + 5
but i'm not sure how you get it >_<

x = 5ac/(a + 5).

Step-by-step explanation:

x/5 + x/a = c

Multiply each term by 5a ( to remove the fractions):

(x*5a) / 5 + (x*5a).a = c*5a

ax + 5x = 5ac          Now factor the left side:

x(a + 5) = 5ac          Divide both sides by (a + 5):

x = 5ac/(a + 5).

the 3rd option is right

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
