Solve 3x+2y=5 and x+y=3 as a graph, substitution, or elimination?

Step-by-step explanation:

multiply second equation by - 2

-2 * (x+y) = 3➡ - 2x - 2y = - 6 now add up both equations

3x + 2y - 2x-2y = 5-6 ➡x = - 1 (-2y eliminated + 2y)

now use the value we found for x in the second equation to find the value of y

x + y = 3 we found x as - 1

-1 + y = 3 ➡y = 4
