Allen subtracts (11x + y) from (ax + 6y). his correct answer is − 10x + 5y. what is the value of a? ***step by step solve

(ax + 6y) - (11x + y)  = -10x + 5y

ax +6y   - 11x - y    = -10x + 5y

(ax - 11x)  + (6y - y) = -10x + 5y

Set the x's equal to the x's and the y's equal to the y's

ax - 11x = -10x           6y - y = 5y

 ax  = 11x -10x              5y = 5y

      ax = x                     5 = 5

       a = 1                      TRUE  (TRUE statement for "y" just means infinite sol'ns)

a = 1

f(x) = y

f(-3) = -5
