Answer 2

1) -3
2) 7
3) 2.4
4) 0.2

Answer 3

Let's solve each of the given equations step by step:

1. 6x = 1 - (4 - 6x)

First, distribute the negative sign inside the parentheses: 6x = 1 - 4 + 6x

Combine the x terms: 6x - 6x = 1 - 4

Simplify: 0 = -3

The equation 6x = 1 - (4 - 6x) has no solutions. There is no value of x that satisfies this equation.

2. 6y - (y - 4) = 4 + 5

First, distribute the negative sign inside the parentheses: 6y - y + 4 = 9

Combine the y terms: 5y + 4 = 9

Subtract 4 from both sides: 5y = 5

Divide both sides by 5: y = 1

The solution to the equation 6y - (y - 4) = 4 + 5 is y = 1.

3. 5.6 - 7y = -4(2y - 0.9) + 2.4

First, distribute the -4 on the right side: 5.6 - 7y = -8y + 3.6 + 2.4

Combine the y terms: 5.6 + 8y = 6

Subtract 5.6 from both sides: 8y = 0.4

Divide both sides by 8: y = 0.05

The solution to the equation 5.6 - 7y = -4(2y - 0.9) + 2.4 is y = 0.05.

4. x - 0.5 = 2(0.3x - 0.2)

First, distribute the 2 on the right side: x - 0.5 = 0.6x - 0.4

Move the x terms to one side and the constants to the other: x - 0.6x = -0.4 + 0.5

Combine the x terms: -0.6x = 0.1

Divide both sides by -0.6: x = -0.1(1/6)

x = -0.1 * (6/1)

x = -0.1 * 6

x = -0.6

The solution to the equation x - 0.5 = 2(0.3x - 0.2) is x = -0.6.

Summary of solutions:

1. The equation 6x = 1 - (4 - 6x) has no solutions.
2. The solution to the equation 6y - (y - 4) = 4 + 5 is y = 1.
3. The solution to the equation 5.6 - 7y = -4(2y - 0.9) + 2.4 is y = 0.05.
4. The solution to the equation x - 0.5 = 2(0.3x - 0.2) is x = -0.6.
