Question

resolva as equações abaixo:

a) 14x+8=10x+16
b) 18x-43=65
c)5b-110+2b=4b-20

Answer 1

A 14x-10x= 16 -8
     4X=8
      X=8/4
      X=2

B 18X=65+43
    18X=108
        X=108/18
        X=6

C   5B+2B-4B= -20+110
      3B=90
        B=90/3
        B=30

Answer 2

14x+8=10x+16
14x-10x=16-8
4x=8
X=8/4
X=2

b)18x-43=65
18x=65+43
18x=108
X=108/18
X=6

C)5b-110+2b=4b-20
5b+2b-4b=-20+110
3b=90
B=90/3
B=30
