Answer 2

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

1. 4.13x - 0.17x = 9.9

Combine like terms on the left side of the equation:

(4.13x - 0.17x) = 3.96x

Now, we have the equation:

3.96x = 9.9

To isolate x, divide both sides by 3.96:

x = 9.9 / 3.96 x = 2.5

So, the solution to this equation is x = 2.5.

2. 5.3x + 4.8x - 5.13 = 43.35

Combine like terms on the left side of the equation:

(5.3x + 4.8x) - 5.13 = 10.1x - 5.13

Now, we have the equation:

10.1x - 5.13 = 43.35

Add 5.13 to both sides of the equation to isolate the variable:

10.1x = 43.35 + 5.13 10.1x = 48.48

Now, divide both sides by 10.1 to find x:

x = 48.48 / 10.1 x ≈ 4.8

So, the solution to this equation is approximately x ≈ 4.8.

3. 1.5 / (2x - 2.4) = 2.5

To isolate the variable, first multiply both sides by (2x - 2.4):

1.5 = 2.5(2x - 2.4)

Now, distribute 2.5 on the right side:

1.5 = 5x - 12

Add 12 to both sides to isolate the variable:

1.5 + 12 = 5x

13.5 = 5x

Now, divide both sides by 5 to find x:

x = 13.5 / 5 x = 2.7

So, the solution to this equation is x = 2.7.
