Question

Resolva as equações
a- X + 2 = 10
b- X - 6 = 8
c- 3x - 21 = 0
d- 6 + X = 6,4
e- 0,5x - 9= 1,5
f- 4x + 3 = 19
g- 5x + 2 = 2x -2
h- 6 - 3x = -10 -4x
i- 2 ( 3x - 5) = 14
j- 2x -1 = 3
_____________

Answer 1

a) x=10-2
x=8

b) x=8+6
x=14

c) 3x=21
x=21/3
x=7

d) x=6,4 - 6
x=0,4

e) 0,5x=1,5+9
0, 5x=10.5
x=10.5÷0,5
x= 21

f)4x=19-3
4x=16
x=16÷4
x=4

g) 5x-2x= -2 (-2)
3x=(-4)
x=(-4)÷3

h) -3x + 4x= -10 + 6
1x= -4
x= -4

i) 6x - 10 = 14
6x = 14 + 10
x=24 ÷ 6
x = 4

j) 2x=3 + 1
x = 4÷2
x = 2
