Question

what should be subtracted from 4a + 16 b + 20 to get -11 a + 2 b - 26

Answer 1

_15a_14b_46 substracted from 4a+16b+20to get _11a+2b-26 .

Answer 2

Let x be subtracted

so.

4a + 16b + 20 - x = - 11a + 2b - 26

x = (4a + 16b + 20 ) - (-11a + 2b -26 )

= 4a + 16b + 20 + 11a -2b +26

= 15a + 14b + 46

so ( 15a + 14b + 46 ) is subtracted from ( 4a + 16b + 20 ) to get ( -11a + 2b - 26 )
