like
X,Y,Z,
1,0,2,3
0,1,2,3

You might want to explain what the matrix you wrote down means. The way I understand it, the last line is solved by x3 = 1.Nope said:Yea, I mean if you can't subtract or do anything on the bottom row, 0,0,1,1
so X3=X3,
is it infinite solutions?
A quick matrix question is a type of survey question that presents multiple rows and columns of response options in a grid format. It allows respondents to select one or more options from each row, making it a more efficient way to collect data on multiple variables at once.
A quick matrix question is useful when you want to gather data on several related variables in a concise manner. It works well for collecting opinions, preferences, and ratings on a scale. However, it may not be appropriate for collecting detailed or open-ended responses.
Most survey software platforms have a feature that allows you to easily create a quick matrix question. Simply select the quick matrix question option and add your rows and columns of response options. You can also customize the layout and design of the grid to fit your needs.
There are several advantages to using a quick matrix question, including saving time and effort for both the respondent and the researcher. It also allows for easy comparison and analysis of responses across multiple variables. Additionally, using a grid format can make the survey more visually appealing and engaging for respondents.
While a quick matrix question can be an effective way to collect data, it may not be suitable for all types of surveys. It may not be appropriate for collecting detailed or open-ended responses, and some respondents may find the grid format confusing or overwhelming. It is important to consider the purpose and audience of your survey before deciding to use a quick matrix question.
