Pomoze ktos błagam potrzebne na jutro rozwiąz równania a)
jedna trzecia (3x-2)= 2
b) 5(x/5-3)=315
C) x+3 podzielic na 2 razy 8 = x-3
d)9 4(2x- trzy czwarte)= 53
E) 2(x+7)=3(2x-5)
F) 3(x-5)+7=x+1

b) 5(\frac{x}{}5-3)=315=
x-15=315=
x=300
c) ((x+3):2)*8=x-3
(x+3)*4=x-3
4x+12 = x-3
3x = (-9)
x = (-3)
d) 4(2x - 3/4) = 53
8x - 3 = 53
8x = 50
x = 6\frac{1}{4}
e) 2(x+7) = 3(2x - 5)
2x + 14 = 6x - 15
2x - 6x = (-15) - 14
(-4x) = (-29)
4x = 29
f) 3 (x - 5) + 7 = x + 1
3x - 15 + 7 = x +1
3x - 8 = x + 1
2x = 9
x = 4,5
