15 - 2 (3 - 2x) = 46

-2 (3-2x) = 46-15

-2 (3-2x) = 31

3-2 = - 31/2

-2x = - 31/2 - 3

-2x = - 37/2

X = 37/2/2

X = 37/2 x 2

X = 37/4

x=33

Step-by-step

subtract 15 and 2 you get 13

13 times 3 = 39

subtract 39 with 39 and 46 with 39

at the end you will get - 26x=7

reverse negative into positive and then add - 26 with 26 and you will be left with x and then you add 7 with 26 and your answer is

x=33
