1. Use PEMDAS to solve equations(Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
First parentheses:
4(x−5)=20
4x-20=20
Second add subtract from both sides by isolating variable x!
4x-20=20
4x=40
4*x=40
x=40/4
x=10
3. Answer: x=10
