Question

1. Resolver las siguientes ecuaciones de ler grado y comprobar la solucion
a) 5[2x-4(3x+1)]=-10x+20
(Soluc: x=-1)
b) x-13=4[3x-4(x-2)]
(Soluc: x=9)
c) 310X-{X-)=15-3(x-3)
(Soluc: x= -1/2)
d) 2x+3(x-3)=6[2x-3(x-5)]
e) x+4[3-2(x-1)]=5[x-3(2x-4)2+1
(Soluc: x=9)
(Soluc: x=41/18)
f) 3-2x+413+5(x+1)=10x-7
(Soluc' x=-21/4)
g) 2(x + 1) + 4(2x + 3) - 1=0
(Sol: x- -2/5)
h) 6(x-3)+2(5x + 8) +5 = -7
(Sol: x=-5/8)
i)5(2x - 3)+ 8(4x - 9)+ 7 - x= x
(Sol: x=2)
i) 3x - 5 +(2x + 1) - 33 - 2x= x+7 (Sol: x=-22)​
