Answer:
Step-by-step explanation:
One of the more obvious "connections" between linear equations is the presence of the same two variables (e. g., x and y) in these equations.
Assuming that your two equations are distinct (neither is merely a multiple of the other), we can use the "elimination by addition and subtraction" method to eliminate one variable, leaving us with an equation in one variable, solve this 1-variable (e. g., in x) equation, and then use the resulting value in the other equation to find the value of the other variable (e. g., y). By doing this we find a unique solution (a, b) that satisfies both original equations. Not only that, but also this solution (a, b) will also satisfy both of the original linear equations.
I urge you to think about what you mean by "analyze connections."
Answer:
-43
Step-by-step explanation:
Using PEMDAS and multiplying first gives you (-5 + 7) - 45
This gives you 2 - 45 which equals -43
Answer:
41?
Step-by-step explanation:
Answer:
Pretty sure it is C
Step-by-step explanation:
Answer:
Steps :
1. Create an equation
If x-4=0 and y-10.4=0, then x - 4 = y - 10.4
2. Isolate variable X by adding 4 to both sides
3. (Optional) Check Answer by plugging given values into the equation
4 = 4 is a true statement
