a)
x - 34 = - 35
x = - 1
4x = 3x - 5
x = -5
b)
64 + 2x = 44 + x
x = - 20
2 - x = - 2x
x = -2
4 + 3x - 2 + 2x
5x + 2
5x = -2
x = - 2/5
x-34 = -35 / +34
x = -1
4x = 3x -5 / - 3x
x= -5
b ) 64 +2x= 44+x / -44
20 +2x = x / - 2x
20 = -x / razy -1
-20 = x
3-x = -2x / +x
3 = x
4+3x -2 +2x = 5x +2
jak bys miała jakies pytania pisz na osobistym :D
