Answer 2

To solve the equations, let's start with the first one:

4(1 - 0.5a) = -2(3 + 2a)

First, distribute the values inside the parentheses:

4 - 2a = -6 - 4a

Next, let's isolate the terms with 'a' on one side of the equation. Add 2a to both sides and add 6 to both sides:

4 + 6 = -2a + 2a - 4a

10 = -2a

Divide both sides by -2:

a = -10/2

Simplifying the expression gives us:

a = -5

Now, let's move on to the second equation:

5(x + 1.2) = 12.5x

First, distribute the value inside the parentheses:

5x + 6 = 12.5x

Next, let's isolate the terms with 'x' on one side of the equation. Subtract 5x from both sides:

6 = 12.5x - 5x

Combine like terms:

6 = 7.5x

Divide both sides by 7.5:

x = 6/7.5

Simplifying the expression gives us:

x = 0.8

Therefore, the solutions to the given equations are:

a = -5 x = 0.8
