Question

Математика: 8x + 12 = 5x + 33(2x + 1) + 7 = 4 6 + 3(5x - 7) = 4x + 73(7x - 4) -- 4(6x + 5) = x3x - 5(2x + 3) - 6(5x - 4) = -283(x+21) + 2(x - 4) = 5(x + 11)​

Пошаговое объяснение:1)8x + 12 = 5x + 3х=-32) Прости не могу3)3(7x - 4) -- 4(6x + 5) = xх=2:11 дробом запиши4)3x - 5(2x + 3) - 6(5x - 4) = -28х=15)3(x+21) + 2(x - 4) = 5(x + 11)​х= пустое множество....

8x + 12 = 5x + 33(2x + 1) + 7 = 4 6 + 3(5x - 7) = 4x + 73(7x - 4) -- 4(6x + 5) = x3x - 5(2x + 3) - 6(5x - 4) = -283(x+21) + 2(x - 4) = 5(x + 11)​

8x + 12 = 5x + 3
3(2x + 1) + 7 = 4 6 + 3(5x - 7) = 4x + 7
3(7x - 4) -- 4(6x + 5) = x
3x - 5(2x + 3) - 6(5x - 4) = -28
3(x+21) + 2(x - 4) = 5(x + 11)
