Question

Resolva as equações:

8 x + 33 = 99

12 x + 4 = 52

Answer 1

8 x + 33 = 99
8 x = 99 - 33
8 x = 66
x=66/8
x=33/4



12 x + 4 = 52
12 x = 52 - 4
12 x = 48
X = 48/12
x = 4

Answer 2

Resolução:

a)

8x + 33 = 99

8x = 99 - 33

8x = 66

x = 66 / 8

x = 33 / 4


b)

12x + 4 = 52

12x = 52 - 4

12x = 48

x = 48 / 12

x = 4
