But that can be time-consuming and confusing - notice that with so many variables and each given inequality including subtraction, you'd have to consider the possibilities of positive and negative numbers for each, numbers that are close together vs. far apart.

X+2y > 16 (our original first inequality). So what does that mean for you here? This matches an answer choice, so you're done. If x > r and y < s, which of the following must also be true? Algebra 2 - 1-7 - Solving Systems of Inequalities by Graphing (part 1) - 2022-23.

With all of that in mind, here you can stack these two inequalities and add them together: Notice that the terms cancel, and that with on top and on bottom you're left with only one variable,. If and, then by the transitive property,. So you will want to multiply the second inequality by 3 so that the coefficients match. Since you only solve for ranges in inequalities (e. g. a < 5) and not for exact numbers (e. a = 5), you can't make a direct number-for-variable substitution. Here you should see that the terms have the same coefficient (2), meaning that if you can move them to the same side of their respective inequalities, you'll be able to combine the inequalities and eliminate the variable.
