3x + y = 15
5x3y = 11
This is an example of a system of equations.
A system of equations is two or more equations that can be graphed, as the solution that satisfies both equations will be the point where the lines intersect on a graph.
Desmos is a graphing calculator, and thus it allows you to visualize this system.
Answer:
D
Step-by-step explanation:
We can see that each X corresponds to a 6, individually. From that, we can assume that the sum of the three Xs is also equal to the sum of three 6s, thus, x+x+x=6+6+6 is viable.
Answer: 4
Step-by-step explanation: You multiplied 2 and 2 which equals to 4
Answer:
Step-by-step explanation:
