x + 75 = 57
x = 57 - 75
x = (-18)
c)
x - 34 = (-35) I+34
x = (-1)
e)
3 - x = (-2x) I+x
3 = (-x)
x = (-3)
i)
7x + 7 = 35 I:7
x + 7 = 5
x = 5 - 7
x = (-2)
j)
2 - x = 5 - 2x I+x
2 = 5 -x
2 - 5 = (-x)
(-3) = (-x)
x = 3
k)
69 - x = x + 96
69 - 96 = x + x
(-27) = 2x I:2
(-13,5) = x
x = (-13,5)
sory że tak mało ale może być Hm?
