Question

resolva a ecuaçao?

a)3x+6=12
b)2=7y - 5
c)5c+2=3-9

​

Answer 1

A) 3x+6= 12

3x= 12-6

3x= 6

x= 6/3= 2

B) 2= 7y- 5

7y= 5+2

7y = 7

y= 7/7 = 1

C) 5c+2= 3-9

5c = 3-9-2

5c = -8

C= -8/5

Answer 2

Resposta:

Oiê, Boa tarde!

a) x-5=8

x=8+5

x=13

b) 3x+6=12

3x=12-6

x=6/3

x=2

c) 2=7y-5

7y=2+5

y=7/7

y=1

d) 5c+2=3-9

5c=-6-2

c= -8/5

c= -1,6

Bons Estudos!!
