Question

Resolva as equações 4x +10 - 2x = 10 - 6x /////6. (x + 2) -2 (x - 4)=20/////2. (5x + 1)= 24 - x

POR FAVOOR! ALGUÉM!?

Answer 1

a) 4x+10-2x= 10 - 6x
4x -2x + 6x = 10 - 10
2x + 6x = 0
8x= 0
x= 0/8
x= 0

b) 6(x+2) - 2(x-4)=20
6x + 12 - 2x - 8 = 20
6x -2x = 20 + 8 - 12
4x = 16
x= 16/4
x= 4

c) 2(5x + 1) = 24 - x
10x + 2 = 24 - x
10x - x = 24 - 2
9x = 22
x= 22/9
