0.4(a - 3) = 0.7(6a - 5) + 1.16 0.4a - 1.2 = 4.2a - 3.5 + 1.16 // раскрываем скобки 0.4a - 4.2a = -1.2 + 1.16 - 3.5 // переносим всё, что содержит a, влево, а все свободные числа — вправо -3.8a = -3.54 a = -3.54 / (-3.8) ≈ 0.93 Ответ: a ≈ 0.93.

0.4a - 1,2= 4.2a-3.5 + 1.16

First, simplify each side of the equation: 0.4*(a-3) = 0.7*(6a-5) + 1.16 0.4a - 1.2 = 4.2a - 3.5 + 1.16 0.4a - 1.2 = 4.2a - 2.34 Next, bring all the variables to one side and all the constant terms to the other side: 0.4a - 4.2a = 1.2 - 2.34 -3.8a = -1.14 Finally, isolate a by dividing both sides by -3.8: a = -1.14 / -3.8 a ≈ 0.3 Therefore, the solution is a ≈ 0.3.
