Which statement is true for the equation 3x − 3x − 2 = −2?It has no solution.
It has one solution.
It has two solutions.
It has infinitely many solutions.

Answers

Answer:

D. It has infinitely many solutions.

Step-by-step explanation:

We have been given an equation $3x-3x-2=-2$ . We are asked to find the number of solutions for our given equation.

We know that an equation has infinitely many solutions, when both sides of the equation are equal.

Let us add 3x on both sides of our given equation.

$3x-3x+3x-2=-2+3x$

$3x-2=3x-2$

Since both sides of our given equation are equal, therefore, our given equation has infinitely many solutions and option D is the correct choice.

It would come out to 3x = 3x so it would be infinitely many solutions

Which equation shows the quadratic formula used correctly to solve 7x2 = 9 + x for x?

Answers

For future reference, use a * to show the multiplication sign because in math x is a variable. 7*2 = 9 + x

Now multiply 7*2= 14

14 = 9 + x

Now subtract 9 from both sides to isolate the x
