Question

1) Resolva as equações, descobrindo o valor da incógnita:
a) X +3 = 26, x vale?
b) 6+ y = 36, y vale?
C) -5+ y = 25, y vale?
d)-1+ a=31 a vale?
e)-11+x=62 x vale?
f)12-19=x x vale?
g)-91 +f= -32 f vale?​

Answer 1

Resposta:

a) x=23, b) y=30 , c) y=30, d) a = 32, e)x = 73

f) x = -7, g) f=59

Explicação passo-a-passo:

a) x +3 = 26

x = 26-3

x =23

b) 6+y = 36

y = 36-6

y = 30

c) -5 + y = 25

y = 25 +5

y = 30

d) -1+a = 31

a = 31+1

a = 32

e) -11+x = 62

x = 62+11

x = 73

f) 12- 19= x

-7 = x

g) -91 + f = -32

f = -32+91

f = 59

Answer 2

Resposta:

a)x + 3 = 26

x = 26 - 3

x = 23

b)6 + y = 36

y = 36 - 6

y = 30

c) -5 + y = 25

y = 25 + 5

y = 30

d) -1 + a = 31

a = 31 + 1

a = 32

e)-11 + x = 62

x= 62 + 11

x = 73

f) 12 - 19 = x

-7 = x

g)-91 + f = -32

f = -32 + 91

f = 59
