rozwiąż równania -3X=2x-10 2x-2+7-x 10=4-2x 0,5y=7-3y -(2x-1)=4 2(x+1)=x 9(x+8)=9x+8 2t-(3t+1)=6 -(4+x)=2(3-x) 4(a-1)=6(1+a) 3(y+6)-y=2(y+9) (x-7)-2(3X+5)=3 Prosze pomóżcie mi

-3X=2x-10 - 3x - 2x = - 10 - 5x = - 10 x = 10/5 = 2 2x-2+7-x - brak znaku równości , wpisz to ci zrobię 10=4-2x - 2x = 4 - 10 2x = 6 x = 6/2 = 3 0,5y=7-3y 3y + 0,5y = 7 3,5y = 7 y = 7/3,5 = 2 -(2x-1)=4 - 2x + 1 = 4 - 2x = 4 - 1 = 3 x = -3/2 2(x+1)=x 2x + 2 = x 2x - x = - 2 x = - 2 9(x+8)=9x+8 9x + 72 = 9x + 8 9x - 9x = 8 - 72 0 = - 64 - sprzeczne 2t-(3t+1)=6 2t - 3t - 1 = 6 - t = 6 + 1 = 7 t = - 7 -(4+x)=2(3-x) - 4 - x = 6 - 2x 2x - x = 6 + 4 = 10 x = 10 4(a-1)=6(1+a) 4a - 4 = 6 + 6a 4a - 6a = 6 + 4 - 2a = 10 a = - 10/2 = - 5 3(y+6)-y=2(y+9) 3y + 18 - y = 2y + 18 3y - 2y - y = 18 - 18 0 = 0 (x-7)-2(3X+5)=3 x - 7 - 6x - 10 = 3 - 5x = 3 + 10 + 7 - 5x = 20 x = - 20/5 = - 4
