Answer 1

15x - 2 = 4x - 13
15x -4x = -13 + 2
11x = - 11
x = -1

Answer 2

For the first question you want to get x on one side then isolate it. do that by subtracting 4x from both sides and adding 2 to both sides as well.
you get this after that 11x = 11 now divide the 11 out to get x =1

Answer 3

1 OR -1 @Fransisco_w

Answer 4

2/3x = 54
2/54 = 3x
1/27 = 3x
x = 3 * 1/27
x = 1/9

Answer 5

Sangya you way wrong on that answer

Answer 6

To get rid of of 2/3 you multiply it by 3/2 on both sides which would look like this...
x = 54 x 3/2
x = 162/2
x = 81

Answer 7

oh and its -1 for the first question :p
