a)
3w+3=4w-5
3w-4w=-5-3
-w=-8 /:(-1)
w=8
b)
½z+6=z-1
½z-z=-1-6
-½z=-7 /:(-½)
z=14
c)
6x-2=7x+5
6x-7x=5+2
-x=7 /:(-1)
x=-7
d)
2(x+6)=-4
2x+12=-4
2x=-4-12
2x=-16 /:2
x=-8
e)
6(1+x)=4(x-1)
6+6x=4x-4
6x-4x=-4-6
2x=-10 /:2

a) 3w+3=4w-5 / -3 , -4w
-w= -8 / * (-1)
w=8
b) 1/2z+6=z-1 /-z , -6
-1/2z= -7 / : (-1/2)
z=14
c) 6x-2=7x+5 / -7x , +2
-x=7 / *(-1)
x=-7
d) 2(x+6)= -4
2x+12= -4 / -12
2x=-16 / :2
x= -8
e) 6(1+x)=4(x-1)
6+6x=4x-4 / -4x, -6
2x= -10 /: 2
x= -5
