Question

(10у+12)*(18-0,3у)=0

Answer 1

(10у+12)*(18-0,3у)=0
10y+12=0
10y=-12
y=-12/10
y1= -1,2
18-0,3y=0
0,3y=18
y=18/0,3
y2=60
Ответ: y1=-1,2; y2=60

Answer 2

(10у+12)*(18-0,3у)=0
(10у+12)*(18*3/10у)=0
(10у+12)*(9*3/5у)=0
(10у+12)*(27/5у)=0
10у+12=0
27/5у=0
у=-6/5
у=0
у=₁=-6/5

Answer 3

To solve the equation (10у + 12) * (18 - 0.3у) = 0, we need to find the values of у (or y) that make the equation true. To do this, we'll use the zero product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be equal to zero.

So, we set each factor in the parentheses to zero and solve for у:

1. 10у + 12 = 0 Subtract 12 from both sides: 10у = -12 Divide both sides by 10: у = -12/10 у = -6/5

2. 18 - 0.3у = 0 Add 0.3у to both sides: 18 = 0.3у Divide both sides by 0.3: у = 18/0.3 у = 60

So, the solutions to the equation are у = -6/5 and у = 60.
