F) 12x-6-4=4X
conta simplificada

Answer 1

2x-4=11-3x
2x+3x=11+4
5x=15
x=15÷5=3

8x-3+1x=4+5x-2
8x+1x-5x=4-2+3
4x=5
x=5÷4= 1,25

1x-1=6x+13x
1x-6x-13x=1
-18x=1
x=1÷-18= 0,05...

10x-5x=10+5
5x=15
x=15÷5=3

4x-16=2x-4
4x-2x=-4+16
2x=12
x=12÷2=6

12x-6-4=4x
12x-4x=6+4
8x=10
x=10÷8=1,25

Answer 2

A) 2x - 4 = 11 - 3x
2x + 3x = 11 + 4
5x = 15
x = 15/5
x = 3

B) 8x - 3 + 1x = 4 + 5x - 2
8x - 3 + x = 2 + 5x
9x - 3 = 2 + 5x
9x - 5x = 2 + 3
4x = 5
x = 5/4

C) 1x - 1 = 6x + 13x
x - 1 = 19x
x - 19x = 1
- 18x = 1 × (- 1)
18x = - 1
x = - 1/18

D) 10x - 5x=10 + 5
5x = 15
x = 15/5
x = 3

E) 4x -16=2x - 4
4x - 2x = - 4 + 16
2x = 12
x = 12/2
x = 6

F) 12x - 6 - 4 = 4x
12x - 4x = 6 + 4
8x = 10
x= 10/8 (÷2)
x= 5/4
