Question

Resolva as equações abaixo

me ajudem por favor ​

Answer 1

a) 2 x + 8 = 240

2x = 240 - 8

2x = 232

x = 232/2

x = 116

b) x + 4 = 16

x = 16 - 4

x= 12

c) 4x = 16

x= 16/4

x= 4

d) 5x = 25

x= 25/5

x= 5

e) 9x+ 18 = 36

9x = 36-18

9x = 18

x = 18/9

x= 2

f) 5x + 9 = 2x + 27

5x - 2x = 27 - 9

3x = 18

x = 18/3

x= 6

g) 2. ( x + 3) = 93

2x + 6 = 93

2x = 93 - 6

2x = 87

x = 87/2

h) 5. (3x+10) = 2. (x + 5)

15x + 50 = 2x + 10

15x -2x = 10 - 50

13x = - 40
