Question

 
3) 10x - 8 - 2 = 7x – 4
4) 2x + 14  = 5x – 1

Answer 1

3°)

10x - 8 - 2 = 7x - 4

10x - 7x = - 4 + 8 + 2

3x = 4 + 2

3x = 6

x = 6/3

x = 2

4°)

2x + 14  = 5x - 1

2x - 5x = - 1 - 14

- 3x = - 15

x = -15/-3

x = 5

Bons Estudos!!!

Answer 2

3) 10x - 8-2=7x-4
10x-10=7x-4
10x-7x = -4+10
3x=6
X = 6 dividido por 3
X= 2

4) 2x + 14 = 5x - 1
2x-5x=-1-14
-3x=-15
X= 5
