Answer 3

Let's solve each of these equations step by step:

a) 3 - 6x = 2 - 4x

First, let's get the variables (x) on one side and the constants on the other side:

3 - 2 = 6x - 4x

1 = 2x

Now, divide both sides by 2 to solve for x:

1/2 = x

So, the solution to the equation is x = 1/2.

b) 2x + (3 - 6x) = -17

First, distribute the 2 on the left side of the equation:

2x + 3 - 12x = -17

Now, combine like terms on the left side:

(2x - 12x) + 3 = -17

-10x + 3 = -17

Next, isolate the variable by moving the constant to the other side:

-10x = -17 - 3

-10x = -20

Now, divide both sides by -10 to solve for x:

x = -20 / -10

x = 2

So, the solution to the equation is x = 2.

d) 2(x + 1) = 3(x - 1)

First, distribute the constants on both sides:

2x + 2 = 3x - 3

Now, move the terms with x to one side and constants to the other side:

2x - 3x = -3 - 2

-x = -5

To solve for x, multiply both sides by -1:

x = 5

So, the solution to the equation is x = 5.
