Hi there!

Answer:
[tex]x = -1[/tex]
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex]5(3 - x)=20[/tex]
[tex](5) (3) + (5)^{(-x)} = 20[/tex] (Distribute)
[tex]15 + -5x = 20[/tex]
[tex]-5x + 15 = 20[/tex]
Step 2: Subtract 15 from both sides.
[tex]-5x + 15 - 15 = 20 - 15[/tex]
[tex]-5x = 5[/tex]
Step 3: Divide both sides by -5.
[tex]\frac{-5x}{-5} = \frac{5}{-5}[/tex]
[tex]x = -1[/tex]
❀Hope this helped you!❀
