Question

3(0.4y+3)-0.6y=8 С пошаговым объяснением

Answer 1

Ответ:

- 5/3

Пошаговое объяснение:

1.2y+9-0.6y=8,

1.2y-0.6y=8-9,

0.6y=-1,

0.6=6/10=3/5

y=-1:(3/5)=- 5/3

Проверка :

3(0.4*(-5/3)+3)-0.6*(-5/3)= 3((-2/3)+3)+1= -2+9+1=10-2=8,

8=8

Answer 2

To solve the equation 3(0.4y + 3) - 0.6y = 8, we will follow these steps: Step 1: Distribute the 3 to the terms inside the parentheses: 3 * 0.4y = 1.2y 3 * 3 = 9 So the equation becomes: 1.2y + 9 - 0.6y = 8 Step 2: Combine like terms: 1.2y - 0.6y = 0.6y 9 - 8 = 1 The equation simplifies to: 0.6y + 1 = 0 Step 3: Move the constant term to the other side of the equation: 0.6y = -1 Step 4: Solve for y by dividing both sides of the equation by 0.6: y = -1 / 0.6 Step 5: Simplify the fraction: y = -1.67 Therefore, the solution to the equation 3(0.4y + 3) - 0.6y = 8 is y = -1.67.
