Answer:
-1
Step-by-step 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
Answer:
x = -1
Step-by-step 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
