Answer:
11+7x
Step-by-step explanation:
Simplifying
9x + 10 + -2x + 1
Reorder the terms:
10 + 1 + 9x + -2x
Combine like terms: 10 + 1 = 11
11 + 9x + -2x
Combine like terms: 9x + -2x = 7x
11 + 7x
Final result:
11 + 7x
I would use long division
Answer:
x=5
Step-by-step explanation:
x-3x can be simplied to -2x and 3-9 can be simplied to -6
-2x+4=-6
Substract 4 from both sides
-2x=-10
Divide both sides by -2
x=5
