Poziom b
d) - 3*(x+7)=-3x-21
e) (x-5)*2=2x-10
f) - 4*(a-3)=-4a+12
poziom c
d)
[tex] \frac{4g - 8h + 1}{2} = 2g - 4h + 0.5[/tex]
e) (3m+6):6= 0,5m+1
f)
[tex] \frac{8t - 4s}{4} = 2t - s[/tex]
Poziom d
d)
[tex] \frac{4t - 8}{4} + ( - 6t + 2s - 1) \div 2 = t - 2 - 3t - s - 0.5 = - 2.5 - 2t - s[/tex]
e) - 6x-(3x-y)+4(-2x+y)=-6x-3x+y-8x-4y=-17x-3y
f)
[tex] \frac{12g + 4}{2} - \frac{10g - 1}{5} = 6g + 2 - 2g + \frac{1}{5} = 4g + 2 \times \frac{1}{5} [/tex]
