Answer:
x=1
Explanation:
First you will distribute it
U basically multiply the 3 by the X and the 7 here
-3 x (x = -3x And the 7 becomes a 21
Then you add the 2
21 + 2 = 23
Then you add the -3
-3x + 23 =20
Then using the equation above you subtract 23 from both sides
(-3 + 23) - 23 = 20 - 23
Then you simplify it
-3x = -3
Then you divide them using the same term
-3
÷ -3
Then you simplfy it and you get
x=1
