Answer 2

It looks like you've provided a set of equations. I'll help you solve them one by one:

1. 19x - 12x = 3,1923 This equation simplifies to: 7x = 3,1923 To solve for x, divide both sides by 7: x = 3,1923 / 7 x ≈ 456.186

2. 3x + 5x + 0.26 = 6.7 Combine the x terms: 8x + 0.26 = 6.7 To isolate the variable, subtract 0.26 from both sides: 8x = 6.7 - 0.26 8x ≈ 6.44 Now, divide by 8 to find x: x ≈ 6.44 / 8 x ≈ 0.805

3. 6x - 11.4 = 3.484 Add 11.4 to both sides of the equation: 6x = 3.484 + 11.4 6x ≈ 14.884 Now, divide by 6 to find x: x ≈ 14.884 / 6 x ≈ 2.48

4. 18 - 12x = 3.22 Subtract 18 from both sides of the equation: -12x = 3.22 - 18 -12x ≈ -14.78 Now, divide by -12 to find x: x ≈ -14.78 / -12 x ≈ 1.232

So, the solutions for x in each equation are approximately:

1. x ≈ 456.186
2. x ≈ 0.805
3. x ≈ 2.48
4. x ≈ 1.232
