Question

The solution to 3x - 8 if x = 9.

Answer 1

To solve the equation 3x - 8 for x = 9, substitute 9 into the equation to get 3(9) - 8, then perform the operations to find the result, which is 19.

Step-by-step explanation:

The student has asked us to find the solution to 3x - 8 when x = 9. To solve this, we simply substitute the value of x into the equation and then perform the arithmetic operations.

1. Substitute x with 9: 3(9) - 8.
2. Multiply 3 by 9: 27 - 8.
3. Subtract 8 from 27: 19.

The solution to the equation 3x - 8 when x equals 9 is 19.

Answer 2

19

Step-by-step explanation:

First, you substitute 9 for x in the equation. Then you use PEMDAS (parentheses, exponents, multiplication, division, addition, and subtraction) to solve it. You multiply 3 by 9 to get 27. Then, you subtract 8 from 27 to get 19.
