Answer:
-5
Step-by-step explanation:
subtract 10 from both sides and subtract 5x from both sides and you’re left with -9x=45. divide both sides by -9 and you’re left with x=-5
- 4x + 10 = 5x + 55
Move 5x to the other side
Sign changes from +5x to -5x
-4x-5x+10= 5x-5x+55
-4x-5x+10= 55
-9x+10= 55
Move 10 to the other side
Sign changes from +10 to -10
-9x+10-10= 55-10
-9x= 45
Divide both sides by -9
-9x/-9= 45/-9
x= -5
Answer: x= -5
