Answer:
x= -3
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.
