And that works well for adding and subtracting, because if we add or subtract the same amount from both sides, it does not affect the inequality Example: Alex has more coins than Billy. If both Alex and Billy get three more coins each, Alex will still have more coins than Billy. No matter, just swap sides, but reverse the sign so it still "points at" the correct value!

My brain immediately says that's greater than or equal toIf they had an audience of 45, in Mesa and another 33, in Denver, how many people attended their show in Las Vegas?

Sal solves several multi-step linear inequalities. If you're seeing this message, it means we're having trouble loading external resources on our website.

So the number of people who attended their show in Las Vegas plus the number that attended their show in Mesa, which is 45, plus the number of people that attended their show in Denver, which is 33, those are three cities right there, Las Vegas, Mesa, and Denver-- that has to be at leastpeople.

Or another way of interpreting that is greater than or equal toSo to figure out how many people attended their show in Las Vegas, we just solve for l on this inequalty.

So if we simplify this left-hand side, we get the number of people in Las Vegas plus-- what's 45, plus 33, that is 78, 78, is going to be greater than or equal toNow to isolate the l on the left-hand side of the inequality, we can subtract 78, from both sides. So minus 78, minus 78, on the left-hand side, these cancel out.

And we're just left with the number of people who attended the show in Las Vegas is going to be greater than or equal tominus 78, Sominus 80, is 40, and it's going to be another 2, So the number of people who attended Las Vegas is going to be greater than or equal to 42, people.

And we're done, that's it.MAFSEE Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all non-negative rational numbers.

Belongs to: Reason about and solve one-variable equations and inequalities. A popular R&B band recently returned from a successful three-city tour where they played to at least , people.

My brain immediately says that's greater than or equal to , LAWS OF EXPONENTS - To multiply powers of the same base, add their exponents.

Thus, 2 2 times 2 3 = 2 5 = 32 PROOF: 2 2 = 4; 2 3 = 8; 2 5 Therefore; 4 x 8 = 32 To divide powers of the same base, subtract the exponent of the divisor from the exponent of the dividend. You are here: Home / Lessons / Intermediate Algebra / Solving Linear Inequalities.
