Question

Решите уравнения.

1)-8(2-2х)+6(-2х+3) =

2)-m(5-n)-n(3+m)+5m =

3)-7(3+2n)+4(5n-3) =

4)-c(3+b)-b(2-c)+3c =

5)3(2-a)+5a =

Answer 1

1)-8(2-2х)+6(-2х+3) = 16 +16x - 12x+18 =  4x + 34

2)-m(5-n)-n(3+m)+5m = -5m + nm - 3n - nm + 5m = -3n

3)-7(3+2n)+4(5n-3) = -21 - 14n +20n - 12 = 6n - 33

4)-c(3+b)-b(2-c)+3c = -3c -bc - 2b + bc = -3c - 2b

5)3(2-a)+5a = 6 - 3a + 5a = 2a + 6
