The lines y = 6x + 3 and y = 105 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.

    6x+3=1056x + 3 = 105
  2. 2

    Subtract 3 from both sides:

    6x+3−3=105−3 ⇒ 6x=1026x + 3 - 3 = 105 - 3 \ \Rightarrow\ 6x = 102
  3. 3

    Divide both sides by 6:

    6x6=1026 ⇒ x=17\frac{6x}{6} = \frac{102}{6} \ \Rightarrow\ x = 17
  4. 4

    Check: put x = 17 back into the equation.
