Question

-314-3.[5+x]=-254

Answer 1

-314 - 3.(5 + x) = -254

3.(5 + x) = -314 + 254

3.(5 + x) = -60

5 + x = -60 : 3

5 + x = -20

x = -20 - 5

x = -25

Answer 2

-314 - 3.(5 + x) = -254

3.(5 + x) = -314 - (-254)

3.(5 + x) = -314 + 254

3.(5 + x)  = -60

5 + x = -60 : 3

5 + x = -20

x = -20 - 5

x = 25
