Answer 2

a) 4m-7=3/4m-7

= 4m-3/4m=7-7

= 4m-3/4m=0

= 16/4m-3/4m=0

= 13/4m=0

= 13/4=m

b) 3z+11=413z+11

= 11-11=413z-3z

= 0 = 410z

= z= 410

c) 4(x+1)=164(x+1)

= 4x+4=164x+164

= -164+4=164x-4x

= -160=160x

= x=-1

d) 2x+14=724x+14

= 14-14=724x-2x

= 0=722x

= x=722

e) 4(x+1)=44(x+1)

= 4x+4=44x+44

= -44+4=44x-4x

= -40=40x

=x=-1
