Best ResponseYou've already chosen the best response.01. Subtract the 2 equations and factor them out and set equal to 0 to solve for x: \[x^22x+3=0\rightarrow (x^2+2x3)=0\rightarrow [(x+3)(x1)]=0\] 2. Then, solve for x: \[x = 3 and 1\] 3. Plug x in to solve for y for 1 solution: \[y = 2x+1\rightarrow y = 2(1)+1\rightarrow y = 3\] 4. Plug in x to solve y for 2nd solution: \[y = 2x + 1\rightarrow y = 2(3)+1\rightarrow y = 5\] 5. Solutions are (1,3) and (3,5)
