· Explain and provide an example of the method used to solve a linear inequality in two variables.
Thank you for the opportunity to help you with your question!
ok for exemple if we have this :
x + 2y = 1
3x - y = 2
so : we take the first equation : x + 2y = 1 so x = 1 - 2y so we take the value of x and we put it on the second equation like :
3(1 - 2y) - y = 2 so : 3 - 6y - y = 2 so : - 7y = -1 so : y = 1/7
so we put the value of y on the first equation : x + 2y = 1
so : x + 2(1/7) = 2 so : x = 2 - 2/7
so : x = 12/7
tel me if this exemple make you undestand or not ???
