Question

1)0,3(6-2y)=4,5-0,7(y+9)

Answer 1

1,8-0,6y=4,5-0,7y-6,3
-0,6y+0,7y=4,5-6,3-1,8
0,1y=-3,6
y= -36

Answer 2

To solve the equation 0.3(6-2y) = 4.5 - 0.7(y+9), follow these steps:

Step 1: Distribute the values inside the parentheses. Step 2: Combine like terms on both sides of the equation. Step 3: Isolate the variable y on one side of the equation. Step 4: Solve for y.

Let's proceed with the solution:

Step 1: Distribute the values inside the parentheses: 0.3 * 6 - 0.3 * 2y = 4.5 - 0.7 * y - 0.7 * 9

Step 2: Simplify the equation: 1.8 - 0.6y = 4.5 - 0.7y - 6.3

Step 3: Combine like terms: 1.8 - 0.6y = -1.8 - 0.7y

Step 4: Isolate the variable y: Add 0.7y to both sides: 1.8 + 0.1y = -1.8

Subtract 1.8 from both sides: 0.1y = -3.6

Now, divide by 0.1 to solve for y: y = -3.6 / 0.1 y = -36

So, the solution to the equation is y = -36.
