What is the solution to the equations?

• one solution

• no solution

• infinite solutions

• none of these

Answer explanation

The equations have the same slope and y-intercept, indicating they represent the same line. Therefore, there are infinite solutions where any point on the line satisfies both equations.

• one solution

• no solution

• infinite solutions

Answer explanation

The equation 9-x=-x+9 simplifies to 9=9, which is always true. This means any value of x satisfies the equation, resulting in infinite solutions.

• one solution

• no solution

• infinite solutions

Answer explanation

To solve the equation 4-2x=2x-4, combine like terms to get 4+4=2x+2x, which simplifies to 8=4x. Dividing both sides by 4 gives x=2. Thus, there is one solution: x=2.

• one solution 

• no solution

• infinite solutions

Answer explanation

The equation 8x + 1 = 8x + 1 is true for all values of x, as both sides are identical. This means there are infinite solutions, as any value of x satisfies the equation.
