Answer 2

Answer:

x =30

Step-by-step explanation:

in order to evaluate the solution 4/5=20/(x-5)?

solution

the first step to take is to cross multiply

4/5=20/(x-5)

we have,

5 x 20 = 4 ( x -5)

100 = 4x - 20

combine the like terms

100+20 = 4x

120 = 4x

divide both sides by the coefficient of x

120/4 = 4x/4

30 = x

x =30

therefore the value of x in the expression 4/5=20/(x-5)? is 30
