a)-8x + 6y - 2=2(-4x+3y-1)
b) 6a - 12b + 18c=6(a-2b+3c)
c)3(x² - 7) + 8(x² - 7 )=11(x²-7)
d)7(x-3)-(x-3)=6(x-3)
e)4(x+5)+20(x+5)=24(x+5)
f)0,2(-10+x)-(x-10)=-0,8(x-10)
a) -8x + 6y - 2 = -2(4x-3y+1)
b) 6a - 12b + 18c = 6(a-2b+3c)
c)3(x do potęgi 2 - 7) + 8(x do potegi 2 - 7 ) = 11(x do potęgi 2 -7)
d)7(x-3)-(x-3) = 6(x-3)
e)4(x+5)+20(x+5) = 24(x=5)
f)0,2(-10+x)-(x-10) = -0,8(x-10)
