Question

(3x+42)·(4,8-0,6x)=0​

Answer 1

Ответ:

3х+42=0

3х=-42

х=-42÷3

х1=-14

4.8-0.6х=0

0.6х=4.8

х=4.8÷0.6

х2=8

вот!

Answer 2

To solve the equation (3x + 42) * (4.8 - 0.6x) = 0, you can use the zero-product property, which states that if the product of two factors equals zero, then at least one of the factors must be equal to zero. In this case, we have two factors:

1. 3x + 42
2. 4.8 - 0.6x

Set each factor equal to zero and solve for x:

1. 3x + 42 = 0 Subtract 42 from both sides: 3x = -42 Divide by 3: x = -14

2. 4.8 - 0.6x = 0 Subtract 4.8 from both sides: -0.6x = -4.8 Divide by -0.6 (which is the same as multiplying by -1/0.6 or -10/6): x = 8

So, the solutions to the equation are: x = -14 and x = 8.
