Hi! I was wondering if anyone might be willing to check my answers for these... I have a suspiscion they are wrong, but I don't have any correct answers to compare them against. If I got them wrong, would you mind giving a brief explanation?
we are doing sloving system of linear equations by substituting 1)y=5x 2x+3y=34 i got (2,10) 2)x=4y 2x+3y=44 i got (16,4) 3)x=4y+5 x=3y-2 i got (-23,-7) 4)y=2x+3 y=4x-1 i got (2,7) 5)4c=3d+3 c=d-1 i got (6,7)
