One Many No Solution

Does this equation have One, Many (infinite) or No Solution?

-2(x + 3) = -2x - 6

• One Solution

• Many (Infinite) Solutions

• No Solutions

Answer explanation

When you distribute -2 on the right side of the equation, the equation will read: -2x - 6 = -2x - 6

Because both sides of the equation are EXACTLY the same value, no matter what you put in for x, the values will always be equal. This means there is an infinite amout of solutions for this problem.

Does this equation have One, Many (infinite) or No Solution?

-3x + 5 = 5x - 3

• One Solution

• Many (Infinite) Solutions

• No Solution

Answer explanation

You can solve this equation, and x = 1.

This is the only possible solution to this problem, so there is only one solution.

Does this equation have One, Many (infinite) or No Solution?

2(x - 3) = 10x - 6 - 8x

• One Solution

• Many (Infinite) Solutions

• No Solution

Answer explanation

The value on the left (2x - 6) is the exact same value as on the right side of the equal sign, so no matter the value of "x" - both sides will always be equal. This means there is an infinite number of solutions.

Does this equation have One, Many (infinite) or No Solution?

5(2x -2) = 2(5x + 5)

• One Solution

• Many (Infinite) Solutions

• No Solution

Answer explanation

When solving this problem, once you eliminate the variable terms from both sides, you are left wiht -10 = 10, and this is NOT a true statement, meaning this equation has NO solution because there is no value that would make this true.

Does this equation have One, Many (Infinite) or No Solution?

7x - 3(x – 2) = 2(2x + 3)

• One

• Many (Infinite) Solutions

• No Solution

Answer explanation

When you distribute and combine like terms on each side, the equation will read 4x + 6= 4x + 6

Because both sides are the same exact value, this equation has infinite solutions because no matter what value you put in for "x", it will always be true.

Does this equation have One, Many (infinite) or No Solution? 2x - 3 = 2x + 7

• One Solution

• Many (Infinite) Solutions

• No Solution

Answer explanation

When you subtract 2x from both sides of the equation, you get -3 = 7.   These values are not equivalent, so there is no possible solution here that would make this equation true.
