Answer 1

Resposta:

c) 5x+7=4x+10

5x-4x=10-7

x= 3

d) 2x+1=4x-7

2x-4x=-7-1

-2x= -8

x= -8/2

x= -4

e) 16x-1=12x+3

16x-12x=3+1

4x= 4

x= 4/4

x= 1

f)5x-3+x=5x+2

5x+x-5x=2+3

x= 5

g) 2x+5-5x=-1

2x-5x= -1-5

-3x= -6

x= -6/3

x= -3

h)5+6x=5x+2

6x-5x= 2-5

x= -3

i) 3x-2x=3x+2

3x-2x-3x= 2

-2x= 2

x= 2/2

x= 1
