Determinati-l pe x din : 8*13-8*8:{13-4*3:[2*11-1*5*(19*2-2*2*x)]+2*2}=100+0:99

Answer 1

8x13-8x8:{13-4x3:[2x11-1x5x(19x2-2x2xX)]+2x2}=100+0:99
8x13-8x8:{13-4x3:[2x11-1x5x(19x2-2x2xX)]+2x2}=100+0
104-64:{13-12:[22-5x(38-4xX)]+4}=100
64:{13-12:[22-5x(38-4xX)]+4}=104-100
64:{13-12:[22-5x(38-4xX)]+4}=4
13-12:[22-5x(38-4xX)]+4=64:4
13-12:[22-5x(38-4xX)]+4=16
13-12:[22-5x(38-4xX)]=16-4
13-12:[22-5x(38-4xX)]=12
12:[22-5x(38-4xX)]=13-12
12:[22-5x(38-4xX)]=1
22-5x(38-4xX)=12:1
22-5x(38-4xX)=12
5x(38-4xX)=22-12
5x(38-4xX)=10
38-4xX=10:5
38-4xX=2
4xX=38-2
4xX=36
X=36:4
X=9
