С ОБЕСЕДОВАНИЯМ!!!! 3=4 (x+2) -7=5 (х+5) 7 (х-1)=3х 5 (х-3)=44 4 (х+6)=х
1) 3 = 4(x + 2) 3 = 4x + 8 4x + 8 = 3 4x = -5 x = - = -1,25 2) -7 = 5(x + 5) -7 = 5x + 25 5x + 25 = -7 5x = -32 x = - = -6,4 3) 7(x - 1) = 3x 7x - 7 = 3x 7x - 3x = 7 4x = 7 x = 4) 5(x - 3) = 44 5x - 15 = 44 5x = 59 x = = 11,8 5) 4(x + 6) = x 4x + 24 = x 4x - x = -24 3x = -24 x = - = -8
