Question

Part 1: Explain, in complete sentences, how you would use the graphing method to solve the following system of equations.

Part 2: Provide the solution to the system.

Part 3: Explain what the solution represents on the graph.

3x + 6y = 18
2x + 5y = 20

Answer 1

Part 1: graph both equations, and see where they intersect.

Part 2:

Substitute something from first equation into the second.

For example, if you work it out, x = -2y + 9

Plug this into the second.

2(-2y+9) + 5y = 20

Solve for y. Plug back in to solve for x.

Part 3: It's where the 2 lines intersect.

Answer 2

Do u know how to graph them?

Answer 3

oh i dont need to graph them for the question
