Inequalities can be solved in the same way as equations, by performing inverse operations on both sides until the variable is isolated. The only difference is that when we divide or multiply by a negative number, we must reverse the inequality sign.
We can solve the inequalities in the same way as equations — we can perform inverse operations on both sides until the variable is isolated. The only difference is that when we divide or multiply by a negative number, we must reverse the inequality sign. Let's do it!
We will solve the given equation using Division Property of Equality. Let's divide both sides of the equation by to isolate
Recall that to divide by a fraction, we need to multiply by its reciprocal.
