Question

Hallar el valor de x
3/5 = 4x-5/7x-8

Answer 1

solo pasa a multiplicar ambos divisores,3(7x-8)=5(4x-5)
21x-24=20x-25
x=-1

Answer 2

3x + 5 = 7x + -8

5 + 3x = 7x + -8

5 + 3x = -8 + 7x

5 + 3x = -8 + 7x

5 + 3x + -7x = -8 + 7x + -7x

5 + -4x = -8 + 7x + -7x

7x + -7x = 0 5 + -4x = -8 + 0 5 + -4x = -8

5 + -5 + -4x = -8 + -5

5 + -5 = 0 0 + -4x = -8 + -5 -4x = -8 + -5

-8 + -5 = -13 -4x = -13

'-4'. x = 3.25
