Hi guys.
I have attempted the following problem and am confused on whether there is an error in my book or not.......
Solve for c and d
-1(x+c) + 9(x+d) = 8x -53
My working:
1) Multiply out and collate terms:
8x - c + 9d = 8x -53
c = -1, d= -6
However my book lists c = 1 and d =6
Could you please help me tackle these
