1. 3x= -24
x= -24÷3
x= -8
2. 4y = 16
y= 16 ÷4
y = 4
3. 7y = 35
y= 35 ÷7
y= 5
4. 9y= 27
y= 27÷ 9
y = 3
5. x/-4= 8
-4x= -32
x= -32/-4
x= 8
6. x/5= -2
5x= -10
x= -10/5
x= -2
7. x/-3 = -5
-3x= 15
x= 15/-3
x= - 5
8. x/-3 = -6
-3x = 18
x= 18 / -3
x= -6
9. 4x -6= -22
4x= -22+6
x= -16/4
x = -4
10. 7x-2= 5x+4
7x-5x= 4+2
2x= 6
x= 6/2
x= 3
11. 4x-2= 2x+20
4x-2x= 20+22
2x= 42
x= 42/2
x= 21
12. x-4= 12
x = 12+4
x= 16
13. 12x +12= 7x-18
12x-7x = -18 -12
5x = - 30
x= -30/5
x = -6
14. 2x+5x-14= 4
7x= 4+14
x= 18/7
x= 2,571..
15. 2x+x+1=4x-1
3x+1=4x-1
1+1=4x-3x
2= x
16. 5x-30=7x+2
-30-2= 7x-5x
-32= 2x
-32/2= x
-16=x
espero q te ayude
