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

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

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.
