im so confused please help me

Answer 1

Explanation:

Ok:

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
