4x + 10 = 5x + 55
what’s the 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

x= -5

probably .5
