Answer:
True
Step-by-step explanation:
You can go about this in two ways.
Solution #1: Substitution
You're asked whether or not x = 20 is a solution to this equation, so you can simply check that by substituting x = 20 into the equation. If the substitution returns 0 = 0, then 20 is a solution.
[tex]x = 20 \to 2(x - 13) = 14\\2(20 - 13) = 14\\2 \times 7 = 14\\14 = 14\\0 = 0[/tex]
Solution #2: Solving
[tex]2(x - 13) = 14 \text{ // Divide by 2}\\x - 13 = 7 \text{ // Add 3}\\x = 20[/tex]
20 is the solution for this equation.
