rozwiąż równania :
a ) - 5 = x = 10 | + 5 x - 34 = - 35 4x = 3x-5
x = 15 x = ? x = ?
b ) 64 = 2x = 44 +x 3 - 34 = - 2x 4 = 3x = 2 + 2x
x = ? x = ? x = ?

A) X-34=-35
x=-35 + 34
x=-1
4x=3x-5
4x-3x=-5
-x=-5
x=5
b
64=2x=44+x
x=44-64
x=-20
3-34=-2x
-2x=31/:-2
x=-15,5
4=3x=2+2x
x=-2
a) x-34=-35
x= -35+34
x= -1
b) 3-34=-2x
2x=34-3
2x=31
x= 31:2
x= 15,5
