-3
-4
1 answer:
Answer:
x = -3
Step-by-step explanation:
You will have to distribute first
7 -2x -11 + 9 -3x = 20
Then, combine you like terms
-2x -3x = -5x
7 -11 +9 =5
Then you write it as an equation
-5x +5 = 20
Next you will want to have x by itself which means you have to get rid of the 5 by substracting 5 on each side (opposite of addition is substraction)
-5x = 15
Then you divide each side by -5 ( opposite of multiplication is division)
x= -3
Hope this helped :D
