Solving a one step equation by subtracting with a negative

The video tutorial explains how double negatives in mathematics can cancel each other out, similar to double negatives in English. It demonstrates rewriting equations to simplify them and using inverse operations to solve for variables. The tutorial provides a step-by-step approach to solving an equation with double negatives, emphasizing the importance of maintaining balance by performing the same operations on both sides of the equation.

What happens when two negative signs are placed next to each other in a mathematical expression?

• They multiply to form a positive.

• They form a zero.

• They remain as two negatives.

• They cancel each other out.

How can you rewrite an equation with two negative signs next to each other?

• By adding a positive sign.

• By ignoring them.

• By converting them into a positive.

• By multiplying them.

What is the first step in solving an equation with a variable?

• Add a constant to both sides.

• Multiply both sides by a constant.

• Undo the operation affecting the variable.

• Divide both sides by a constant.

When solving the equation X + 74 = -22, what operation should be performed?

• Add 74 to both sides.

• Multiply both sides by 74.

• Subtract 74 from both sides.

• Divide both sides by 74.

If both numbers in an equation are negative, what can you infer about their sum?

• The sum will be positive.

• The sum will be zero.

• The sum will be negative.

• The sum will be undefined.
