3(1/3x + 4 ) =45
5(2x - 3) = 4 ( x - 3 )
- ( 6 + x ) = 2 ( x/4 - 2 ) +1
Bardzo proszę o obliczenia , nie o same wyniki
PS. W ostatnim zadaniu ten - na początku jest specjalnie. ;)

3 * x + 4 = 45
1x + 12 = 45
x = 45 - 12
x = 33
5 * (2x - 3) = 4 * (x - 3)
10x - 15 = 4x - 12
10x - 4x = -12 + 15
6x = 3 | :6
x =
- (6 + x) = 2 * ( - 2) +1
-6 -x = x - 4 + 1
-x + x = -4 + 1 +6
x = 3
