Calculate expr

Calculate the example with decimal numbers:

-5 + (- 14 + 11) • [24-2 • (-0,4)] - {- 28-41 • [-8 • 2 + 4 • 1 • (0,1-2,4)] + 1} =

Correct answer:

x =  48.4

Step-by-step explanation:

x = −5+(−14+11)•[24−2•(−0,4)]−{−28−41•[−8•2+4•1•(0,1−2,4)]+1} a=−14+11=−3 b=24−2⋅ (−0.4)=24.8 c=4⋅ 1⋅ (0.1−2.4)=−9.2 d=−8⋅ 2+c=−8⋅ 2+(−9.2)=−5126​=−2551​=−25.2 e=4⋅ 1⋅ d=4⋅ 1⋅ (−25.2)=−5504​=−10054​=−100.8  x=−5+a⋅ b−(−28+e+1)=−5+(−3)⋅ 24.8−(−28+(−100.8)+1)=5242​=4852​=48.4  Verifying Solution:  x1​=−5+(−14+11)⋅ (24−2⋅ (−0.4))−(−28−4⋅ 1⋅ (−8⋅ 2+41⋅ (0.1−2.4))+1)=−493.6
