Question

Aflați x din egalitatea [20 x( X: 40 - 24 ) x 7500 : 15 - 9980 ]x 40 = 800

Answer 1

Răspuns

x = 1000

Explicație pas cu pas:

[20 x (x/40-24) x 7500/15 - 9980] x 40 = 800

20 x (x/40-24) x 7500/15 - 9980 = 800 / 40

20 x (x/40-24) x 7500/15 - 9980 = 20

20 x (x/40-24) x 7500/15 = 20 + 9980

20 x (x/40-24) x 7500/15 = 10 000

(x/40-24) x 7500 / 15 = 10 000 / 20

(x/40-24) x 7500 / 15 = 500

(x/40-24) x 7500 = 500 x 15

(x/40-24) x 7500 = 7500

x/40-24 = 7500 / 7500

x/40-24 = 1

x/40 = 1 + 24

x/40 = 25

x = 25 x 40

x = 1000
