Concept explainers
To explain: The coefficients of x and y in standard form of a linear equation can mnot both be zero.
Answer to Problem 44PPE
If coefficients of both x and y in standard form of a linear equation will be zero, then it will take the form
Explanation of Solution
Given information: Linear equation in two variables x and y in standard form is given as:
Concept used: Linear equations are used to solve real life situation that are linear in nature and are set for two unknown quantities. Thus, if the coefficients of these unknown variables will be zero, then no linear equation can be formed to get these unknown variables. Thus, at-least one variable`s coefficient should at least be non-zero.
Conclusion: So, for the existence of the linear equation, it is a must that the coefficients of both the unknown variables in the linear equation can never be zero.

B A C FIGURE 1. For Problem (7). Let x₁ be the number of users at website A. Let x2 be the number of users at website B. Let x3 be the number of users at website C. Assume that there are a total of 900 users at these three websites. This gives us the following system of linear equations: x1 = x2 + 1x3 x2 = x1 + x3 x3 = x2 = 900 x1 + x2 + x3 = (a) Put this system into a standard form (with all variables on the left side and with the constants on the right), and convert that system into an augmented matrix, and then...
