Step-by-Step Solution

To solve the equation 70x+43+69=68x15x 70x + \frac{4}{3} + \frac{6}{9} = 68x - 15x , let's proceed with the following steps:

First, simplify the fractions on the left side. Notice that 69\frac{6}{9} simplifies to 23\frac{2}{3}.

So the equation becomes:

70x+43+23=68x15x 70x + \frac{4}{3} + \frac{2}{3} = 68x - 15x

Next, combine the fractions on the left side:

70x+(43+23)=68x15x 70x + \left(\frac{4}{3} + \frac{2}{3}\right) = 68x - 15x

This results in:

70x+63=68x15x 70x + \frac{6}{3} = 68x - 15x

The fraction 63\frac{6}{3} simplifies to 2, resulting in:

70x+2=68x15x 70x + 2 = 68x - 15x

Now, simplify the right side by combining like terms:

70x+2=53x 70x + 2 = 53x

Subtract 53x 53x from both sides to isolate terms involving x x on one side:

70x53x+2=0 70x - 53x + 2 = 0

This simplifies to:

17x+2=0 17x + 2 = 0

Subtract 2 from both sides to isolate the term with x x :

17x=2 17x = -2

Finally, divide both sides by 17 to solve for x x :

x=217 x = -\frac{2}{17}

Therefore, the solution to the problem is x=217 x = -\frac{2}{17} .

Answer

217 -\frac{2}{17}
