Question

4. Aflaţi x din egalitatea 24+ [200 – (987 – 13x)] · 2 = 270​

Answer 1

24+ [200 – (987 – 13x)] · 2 = 270

[200 – (987 – 13x)] · 2 = 270-24=246

200 – (987 – 13x) =246:2=123

987 – 13x =200-123

987 – 13x =77

13x=987-77

13x=910

x=70

Answer 2

Răspuns: x = 70

Explicație pas cu pas:

24 + [200 - (987 - 13x)] · 2 = 270​

[200 - (987 - 13x)] · 2 = 270​ - 24

[200 - (987 - 13x)] · 2 = 246

200 - (987 - 13x) = 246 : 2

200 - (987 - 13x) = 123

200 = 123 + (987 - 13x)

200 - 123 = (987 - 13x)

77 = 987 - 13x

77 + 13x = 987

13x = 987 - 77

13x = 910

x = 910 : 13

x = 70
