Answer:
Step-by-step explanation:
5x - 40 = 20
5x = 20 + 40
5x = 60
x = 60/5
x = 12

Order of Operations: BPEMDAS
Equality Properties
<u>Step 1: Define equation</u>
5(x - 8) = 20
<u>Step 2: Solve for </u><em><u>x</u></em>
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
Here we see that 20 does indeed equal 20.
∴ x = 12 is a solution to the equation.
The Answer is P = (-2.5 , 1 )
Let, the point is P(x,y)
then,
=>
∴
Again,
Thus, P = (-2.5 , 1 )
