Question

por favor, necesito ayuda. hallar la solicion y comprobar 4x+5=4{-2[2(x-1)-3(x+5)]}

Answer 1

4x+5=4{-2[2(x-1)-3(x+5)]}
4x+5=4{-2[2x-2-3x-15]}
4x+5=4{-2[-x-17]}
4x+5=4{2x+34}
4x+5=8x+136
8x-4x=5-136
4x=-131
x=-131/4

4x+5=4(-131/4) + 5 = -131+5 = -126
4{-2[2(x-1)-3(x+5)]} =
 4{-2[2(-131/4-1)-3(-131/4+5)]} =
 4{-2[-131/2-2+(3)(131)/4-15]} = 
4{131+4-(3)(131)/2+(15)(2)}  = 
4(131)+16-(6)131+(8)15 =
-2(131)+136=-126
