The lines y = 10x + 4 and y = 134 meet at x = 13. 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+4=13410x + 4 = 134
  2. 2

    Subtract 4 from both sides:

    10x+4−4=134−4 ⇒ 10x=13010x + 4 - 4 = 134 - 4 \ \Rightarrow\ 10x = 130
  3. 3

    Divide both sides by 10:

    10x10=13010 ⇒ x=13\frac{10x}{10} = \frac{130}{10} \ \Rightarrow\ x = 13
  4. 4

    Check: put x = 13 back into the equation.
