Me ajudem por favor

Answer 1

1)
a) 6x - 2x = 12
4x = 12 
x = 12/4
x = 3
b) 2x - x = 1 + 5
x = 4
c) 2x - x = 4 - 3
x = 1
d) 2x = 12 - 10
x = 2/2 
x= 1
e) 4x - x = 2 + 10
3x = 12
x = 12/3
x = 4
2) 
a) 6x - 2x = 9 + 3
4x = 12
x = 12/4
x= 3
b) 10x - x = 18
9x = 18
x = 18/9
x = 2
c) 2x = 17 - 4
2x = 13
x = 6,5
d) 3x - 4x = -9 + 2
x = 7
