Answer 2

To solve the given equations:

1. 34(x + 1.2) - 1.2 = 60

Let's simplify the equation:

34x + 34(1.2) - 1.2 = 60 34x + 40.8 - 1.2 = 60 34x + 39.6 = 60

Next, we'll isolate the variable 'x' by subtracting 39.6 from both sides of the equation:

34x + 39.6 - 39.6 = 60 - 39.6 34x = 20.4

Finally, we'll solve for 'x' by dividing both sides of the equation by 34:

34x/34 = 20.4/34 x = 0.6

Therefore, the solution to the equation is x = 0.6.

2. 295.1 : (x - 3) - 12.7 = 0.3

Let's simplify the equation:

295.1 / (x - 3) - 12.7 = 0.3

First, let's get rid of the fraction by multiplying both sides of the equation by (x - 3):

295.1 = 0.3(x - 3) + 12.7

Now, let's distribute the 0.3 to the terms inside the parentheses:

295.1 = 0.3x - 0.9 + 12.7

Combine the constant terms:

295.1 = 0.3x + 11.8

Next, isolate the variable 'x' by subtracting 11.8 from both sides of the equation:

295.1 - 11.8 = 0.3x + 11.8 - 11.8 283.3 = 0.3x

To solve for 'x', divide both sides of the equation by 0.3:

283.3 / 0.3 = 0.3x / 0.3 944.33 = x

Therefore, the solution to the equation is x ≈ 944.33.
