b) 2x-12=-20
c) 7x-9=4x-6

Pfv me ajudem

Answer 1

a) 6x-6=10+2x
6x-2x=10 + 6
4x=16
X= 16/4
X= 4
b) 2x-12=-20
2x=-20 +12
2x=-8
X=-4
c)7x-9=4x-6
7x -4x = -6+9
3x=3
X=1

Answer 2

Olá

a)
6x - 6 = 10 = 2x
6x - 2x = 10 + 6
4x = 16
x = 16/4
x = 4

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

c)
7x - 9 = 4x - 6
7x - 4x = - 6 + 9
3x = 3
x = 3/3
x = 1
