Answer:

x = -1

Explanation:

simplfy to 21x + 8 = -9x -22

add 9x to get 30x + 8 = -22

then subtract 8 to get 30x =-30

divide by 30 and you get x = -1

Answer:

-1

Explanation:

-isolate everything with x on one side and without x on the other side

-remember if you pass the equal sign change the sign of that term

13x+8x+9x = -22-8

-combine like terms

30x = -30

-divide both sides by 30

x= -1
