Question

c)33+z=5-3z

d) 7x-33=-12​

Answer 1

c)33+z=5-3z

z + 3z = 5 - 33

4z = - 28

z= - 28/4

z= - 7

d) 7x-33=-12

7x = - 12 + 33

7x = 21

x= 21/7

x= 3

Answer 2

Explicação passo-a-passo:

33+z = 5—3z

z+3z = 5—33

4z = —28

z = —28/4

z = —7

7x — 33 = —12

7x = —12+33

7x = 21

x = 21/7 = 3
