Question

Resolva as Equações a seguir:
a)x+1=5
b)x+12=21
c)x+3-5=15
d)3+2x-2-x=5
e)3x-6=2x+1
f)2x=4

Answer 1

Isole X!

a)x+1=5

x = 5 - 1

x = 4

b)x+12=21

x = 21-12

x = 9

c)x+3-5=15

x -2 = 15

x = 15 + 2

x = 17

d)3+2x-2-x=5

x = 5 - 3 + 2

x = 4

e)3x-6=2x+1

3x - 2x = 1 + 6

x = 7

f)2x=4

x = 4/2

x = 2
