The lines y = 10x + 8 and y = 178 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+8=17810x + 8 = 178
  2. 2

    Subtract 8 from both sides:

    10x+8−8=178−8 ⇒ 10x=17010x + 8 - 8 = 178 - 8 \ \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.
