0,2y - 4,5) : 7 = -1,2 решение 10 баллов СРОЧНО!1!1!1!

Answer 1

0,2у-4,5=-1,2*7

0,2у-4,5=-8,4

0,2у=-8,4+4,5

0,2у=-3,9

у=-3,9:0,5

у=-7,8

Answer 2

To solve the equation (0.2y - 4.5) / 7 = -1.2, we'll follow these steps:

Step 1: Multiply both sides of the equation by 7 to eliminate the denominator: 7 * ((0.2y - 4.5) / 7) = 7 * (-1.2)

Simplifying: 0.2y - 4.5 = -8.4

Step 2: Add 4.5 to both sides of the equation to isolate the term with 'y': 0.2y - 4.5 + 4.5 = -8.4 + 4.5

Simplifying: 0.2y = -3.9

Step 3: Divide both sides of the equation by 0.2 to solve for 'y': (0.2y) / 0.2 = (-3.9) / 0.2

Simplifying: y = -19.5

Therefore, the solution to the equation (0.2y - 4.5) / 7 = -1.2 is y = -19.5.
