Question

Boa noite!
Gostaria de saber o resultado dessa fração.
a) 32+x=247

b) 5x-2=58

c) 2.x+x+10=70

d) 3.x+4.x=49

e) 5.x-10=80

Answer 1

a) 32+x=247
x = 247 - 32
x = 215

b) 5x-2=58
5x = 58 + 2
5x = 60
x = 12

c) 2.x+x+10=70
3x = 60
x = 20

d) 3.x+4.x=49
7x = 49
x = 7

e) 5.x-10=80
5x = 90
x = 90/5
x = 18

Answer 2

a) 32 + x = 247
x= 247 -32
x=215

b) 5x- 2 =58
5x = 58+2
5x = 60
x=60/5
x= 12

c) 2x + x + 10 = 70
3x = 60
x= 60/3
x= 20

d) 3x + 4x = 49
 7x = 49
x= 49/7
x= 7

e) 5.x -10 = 80
5x = 10 + 80
5x = 90
x= 90/5
x= 18
