The lines y = 10x + 3 and y = 173 meet at x = 17. The solution of the equation is the x-coordinate of the point where the two sides are equal.

How to work it out

  1. 1

    The goal is to get x alone. Undo the operations in the opposite order: first the addition, then the multiplication.

    10x+3=17310x + 3 = 173
  2. 2

    Subtract 3 from both sides:

    10x+3−3=173−3 ⇒ 10x=17010x + 3 - 3 = 173 - 3 \ \Rightarrow\ 10x = 170
  3. 3

    Divide both sides by 10:

    10x10=17010 ⇒ x=17\frac{10x}{10} = \frac{170}{10} \ \Rightarrow\ x = 17
  4. 4

    Check: put x = 17 back into the equation.
