Question 1:
The given equation is 7x − 6 + 3 = 5x + 2x + 5.
To solve this equation, we can simplify both sides by combining like terms:
7x - 3 = 7x + 5
Next, we can subtract 7x from both sides to eliminate the variable:
-3 = 5
Since this leads to a contradiction, there are no solutions for the given equation.
Therefore, the correct answer is D) no solution.
Question 2:
To determine the equation with infinitely many solutions, we need to find an equation where any value for the variable satisfies the equation.
Looking at the given options, we can see that option A) 9x − 3 = 3x + 6x + 2 + 39x − 3 = 3x + 6x + 2 + 3 can be simplified as follows:
9x - 3 = 9x + 5
By subtracting 9x from both sides, we get:
-3 = 5
Similar to the previous question, this leads to a contradiction and there are no solutions for this equation. Therefore, option A) does not have infinitely many solutions.
None of the other options seem to have the same pattern where any value for the variable satisfies the equation. Hence, the correct answer is none of the given options.
