Answer:

x= -41/10

Step-by-step explanation:

2x-9/5= -10

2x= -10+9/5

2x= -41/5

(divide on both sides)

x= -41/10
x = -20.5

First, we have to multiply each side by 5. This gets rid of the fraction. This leaves you with 2x - 9 = -50.

You want to get x alone on one side, so next you add nine to both sides.

2x = 41

Finally, divide both sides by 2

x = -20.5

To check this, substitute 20.5 for x in your original equation.

(2(-20.5) - 9)/5 = -10
(-41 - 9)/5 = -10
-50/5 = -10
-10 = -10
Both sides equal each other, so -20.5 is the right answer
