 Question 118133: Find the values for m and b in the following system so that the solution to the system is (-3,4). 5x + 7y =b and mx + y =22. First; 5x+7y=b, =>5(-3)+7(4)=b, =>-15+28=b, =>13=b. Now this one; mx + y=22; =>m(-3)+4=22, =>-3m=22-4=18, =>-3m=18, =>m=18/(-3), =>m=-6. So then b=13 and m=-6. I just want to know if I am correct please?
