Step-by-Step Solution

To solve the equation 16x30x+1.5=3.4+0.8+10x 16x - 30x + 1.5 = 3.4 + 0.8 + 10x , we follow these steps:

  • Simplify both sides by combining like terms.
    On the left side: 16x30x=14x 16x - 30x = -14x
    The left side becomes: 14x+1.5 -14x + 1.5
    On the right side: 3.4+0.8=4.2 3.4 + 0.8 = 4.2
    The right side becomes: 4.2+10x 4.2 + 10x
  • Re-arrange the equation to move all x x terms to one side and constant terms to the other:
    Start from 14x+1.5=4.2+10x -14x + 1.5 = 4.2 + 10x
  • Subtract 10x 10x from both sides to get all x x terms on one side:
    14x10x+1.5=4.2 -14x - 10x + 1.5 = 4.2
    Thus, we have 24x+1.5=4.2 -24x + 1.5 = 4.2 .
  • Subtract 1.5 1.5 from both sides to isolate terms with x x :
    24x=4.21.5 -24x = 4.2 - 1.5
    24x=2.7 -24x = 2.7
  • Finally, divide both sides by 24-24 to solve for x x :
    x=2.724=0.1125 x = \frac{2.7}{-24} = -0.1125
    Rounding to two decimal places, x0.11 x \approx -0.11 .

Therefore, the solution to the equation is x=0.11 x = -0.11 .

Answer

0.11 -0.11
