Question

Математика: Найди корни уравнений 3(x-2)=4x 6(z-1)=18 5(y+3)=10 3(2x-7)=9 -4(x-2)=-6 3(x-5)=x+3

utopia2 · Answer

3(x-2)=4x3х - 6 = 4х-х = 6 |×(-1)х = -66(z-1)=186z - 6 = 18 6z= 18 +6 6z = 24z = 45(y+3)=105y + 15 = 105y= 10 - 155y = -5 y = -13(2x-7)=96x - 21 = 9 6x = 21 + 96x = 30x = 5 -4(x-2)=-6 -4x +8 = -6-4x = -6-8 -4x = -14|÷ (-4)x = 7/23(x-5)=x+33x-15 = x+33x-x = 15+32x = 18x = 9...
