Respuesta :

1. X = 7
2. X=6
3. X=-8
4. X= 3 (I round it to the nearest number of 2.6)
1. -4x= -28
28/4= 7
x=7

2. 4(x+1)= -28
4x+4=-28
-28-4= -32
-32/4= -8
x=-8

3. x-7= -1
x= 6
in these types of question all you have to is subtract one from the other number.

4. -3x + 7= -1
-1-7=-8
-8/-3
2.6 repeating (2.666666666)
