Question

Me ajudem
A) -3x=12
B) 5x=60
C) y+36 = 26
D) X-18=18
E) 3y+28=1
F)12x-20=16

Answer 1

a) - 3x = 12

x = 12/-3

x = - 4

___________

b) 5x = 60

x = 60/5

x = 12

_____________

c) y + 36 = 26

y = 26 - 36

y = - 10

_______________

d) x - 18 = 18

x = 18 + 18

x = 36

_______________

e) 3y + 28 = 1

3y = 1 - 28

3y = - 27

y = - 27/3

y = - 9

________________

f) 12x - 20 = 16

12x = 16 + 20

12x = 36

x = 36/12

x = 3

Answer 2

A) -3x=12
X=-4

B) 5x=60
12

C) y+36=26
y=26-36
Y= -10

D) x-18=18
x=18+18
X=36

E)3y+28=1
3y=1-28
3y=27
Y=9

F)12x-20=16
12x=16+20
12x=36
X=3
