Question

a) x+4 =12
b) X-5=19
c) 5+ x = 22-10
d) 24+ x = 48+2
e) 3+x+4= 6+1+8​

Answer 1

Resposta:

a) x = 12-4= 8

b) x-5= 19

x = 19+5

x = 23

c) x = 12-5

x = 7

d) x = 50-24

x = 26

e) x = 15 -4 -3

x = 8

Answer 2

Resposta:

a) x = 8

b) x = 24

c) x = 7

d) x = 26

e) x = 8

Explicação passo-a-passo:

$a) \: x + 4 = 12 \\ x = 12 - 4 \\ \bf{x = 8}$

$b) \: x - 5 = 19 \\ x = 19 + 5 \\ \bf{x = 24}$

$c) \: 5 + x = 22 - 10 \\ 5 + x = 12 \\ x = 12 - 5 \\ \bf{x = 7}$

$d) \: 24 + x = 48 + 2 \\ 24 + x = 50 \\ x = 50 - 24 \\ \bf{x = 26}$

$e) \: 3 + x + 4 = 6 + 1 + 8 \\ x + 7 = 15 \\ x = 15 - 7 \\ \bf{x = 8}$

Espero ter ajudado! :)
