Question

Answer two questions about equations aaaa and bbbb:
a. 3x−1=7
b. 3x=8

Answer 1

Both equations, 3x - 1 = 7 and 3x = 8, have the same solution, which is x = 8/3 or approximately x = 2.67 after isolating the variable and dividing each side by 3. a. 3x−1=7 is correct answer.

Step-by-step explanation:

To solve the equations 3x - 1 = 7 (equation aaaa) and 3x = 8 (equation bbbb), follow these steps:

Equation aaaa: 3x - 1 = 7

1. Add 1 to both sides of the equation to isolate the term with the variable: 3x - 1 + 1 = 7 + 1, which simplifies to 3x = 8.
2. Divide both sides of the simplified equation by 3 to find the value of x: 3x / 3 = 8 / 3, which gives us x = 8/3 or approximately x = 2.67.

Equation bbbb: 3x = 8

1. Divide both sides of the equation by 3 to find the value of x: 3x / 3 = 8 / 3, which gives us x = 8/3 or approximately x = 2.67.

By solving both equations aaaa and bbbb, we can see that they have the same solution: x = 2.67.
