Answer 2

To solve the given equations:

1. 1.7x + 2.04 = -6.8x

Let's start by simplifying the equation by combining like terms:

1.7x + 6.8x = -2.04

Adding the x terms:

8.5x = -2.04

Now, isolate x by dividing both sides of the equation by 8.5:

x = -2.04 / 8.5

x ≈ -0.24

Therefore, the solution to the equation is x ≈ -0.24.

2. -5 × (4x + 3) + 3x = -12 × (x - 3)

First, distribute the -5 and -12 on their respective parentheses:

-20x - 15 + 3x = -12x + 36

Combine like terms:

-20x + 3x - 12x = 36 + 15

-29x = 51

Next, isolate x by dividing both sides of the equation by -29:

x = 51 / -29

x ≈ -1.76

Therefore, the solution to the equation is x ≈ -1.76.
