Question

1) RESOLVA AS EQUAÇÕES.
a) A-2 = 10
b) L+3 = 1
c) E-3=-1
d) 2.X +4= 6
e) 3.A - 8 = 13​

Answer 1

A) A-2 = 10

A = 10+2

A = 12

B) L+3 = 1

L = 1-3

L = -2

C) E-3 = -1

E = -1+3

E = 2

D) 2X+4 = 6

2X = 6-4

2X = 2

X = 2/2

X = 1

E) 3A-8 = 13

3A = 13+8

3A = 21

A = 21/3

A = 7

Answer 2

Resposta:

a) A=12 12-2=10

b)L= -2 -2 + 3= 1

c) E= 2 2 - 3 = -1

d) X= 1 2 . 1 + 4 = 6

e) A= 7 3 . 7 - 8 = 13
