Question

Which is a solution of the equation 5(x-8) = -55

Answer 1

Answer:

x = -3

Step-by-step explanation:

5(x-8) = -55

Divide each side by 5

5/5 (x-8) = -55/5

x-8 = -11

Add 8 to each side

x-8+8 = -11 +8

x = -3

Answer 2

Answer:

x= -3

Step-by-step explanation:

To solve the equation, we want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

5(x-8)= -55

x-8 is being multiplied by 5. The opposite of multiplication is division. Divide both sides by 5.

5(x-8)/5= -55/5

(x-8)= -55/5

(x-8)=-11

8 is being subtracted from x. The opposite of subtraction is addition. Add 8 to both sides.

x-8+8= -11+8

x= -11+8

x= -3

Let's check our solution. Plug -3 in for x in the original equation.

5(x-8)=-55

5(-3-8)= -55

5(-11)=-55

-55=-55

This is true, so we know that x is equal to -3.
