Me ajuda pfvr❤

Answer 1

Resposta:

A) 5z -2z= 3

3z =3

z= 3/3 = 1

B) 7k-3k=12-9

4k= 3

k= 3/4

C) 5e+3e+e= 10+8

9e = 18

e = 18/9 = 2

D) 3x+3 = 6

3x = 6-3

3x = 3

x = 3/3 = 1

E) 2y-4y = -5-1

-2y = -6 ×(1)

2y = 6

y = 6/2 = 3

F) 6u = 3-9

6u = -6

u = -6/6 = -1

G) 6t-10 = 8

6t = 8 +10

6t = 18

t = 18/6 = 3
