The equation to be solved is x = 17x - 70.

Move all the terms with x to one side.

x = 17x - 70

=> x - 17x = -70

=> -16x = -70

=> 16x = 70

x = 70/16

The required solution for x = 70/16

If this is really all there is to the equation, here is how you do it:

You have

x = 17x - 70

First, you need to get all the x terms on one side.  You do this by subtracting 17x from both sides.  Now you have

-16x = -70

Now, you divide both sides by -16.  That gives you

x = 4.375

To find the solution of x=(17x-70) just bring the terms with x to one side and take the numerical terms to the other side.

x=(17x-70)

Subtract 17x from both the sides

x - 17x = 17x - 17x - 70

-16x = -70

Divide both the sides by -16

(-16x)/(-16) = (-70)/(-16)

x = 35/8

The solution of the equation is x = 35/8

It is a linear equation and we'll isolate the unknown x to the left side. For this reason, we'll subtract 17x both sides:

x - 17x = -70 + 17x - 17x

We'll combine and eliminate like terms both sides:

-16x = -70

We'll divide by -16:

x = 70/16

x = 4.375

The only solution of the equation is x = 4.375 (decimal form).
