Question

a) 2(b+1)=4(b+2)
b) 4-(1-2c)=-6+(3c+5
c) 3(d-4)+1=2(d-6)+4
d) e(e-2)+3=24-e(5-e)
e) 5(f+3)=-3-(-2-7f)

Answer 1

a) 2(b+1)=4(b+2)
2b+2=4b+8
2b+4b=8-2
-2b=6
-b=6/2
-b=3
b=-3

b) 4-(1-2c)=-6+(3c+5)
4-1+2c=-6+3c+5
3+2c =-1+3c
2c-3c=-1-3
-c=-4
c=4

c) 3(d-4)+1=2(d-6)+4
3d-12+1=2d-12+4
3d-11=2d-8
3d-2d=-8+11
d=3


e) 5(f+3)=-3-(-2-7f)
5f+15=-3+2+7f
5f-7f=-1-15
-2f=-16
f=-16/-2
f=8

d) e(e-2)+3=24-e(5-e)
e (cuadrado) -2e+3=24-5e-e (cuadrado)
2e (cuadrado) +3e-21=0
(tenes que hacer la cuadratica, esta te la debo disculpa)
