Answer 1

Ответ:

(4a-5a+3)-(14a-15ax)

4a-5a+3-14a+15ax

4a-5a-14a+15ax=-3

-15a+15ax=-3

-15a(1-x)=-3

-15a=-3; a=5

1-x=-3; x=4

Answer 2

To simplify the expression (4a - 5a + 3) - (14a - 15ax), we'll first distribute the negative sign inside the second set of parentheses:

= 4a - 5a + 3 - 14a + 15ax

Next, we'll combine like terms:

= (-5a - 14a) + (4a + 15ax) + 3

= -19a + 4a + 15ax + 3

= -15a + 15ax + 3

So, the simplified expression is -15a + 15ax + 3.
