Explain it step by step in chatMake a short video of it
The lines y = 10x + 15 and y = 15 meet at x = 0-6-4-2246-40-2020406080x = 0y = 10x + 15y = 15
The lines y = 10x + 15 and y = 15 meet at x = 0. 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+15=1510x + 15 = 15
  2. 2

    Subtract 15 from both sides:

    10x+15−15=15−15 ⇒ 10x=010x + 15 - 15 = 15 - 15 \ \Rightarrow\ 10x = 0
  3. 3

    Divide both sides by 10:

    10x10=010 ⇒ x=0\frac{10x}{10} = \frac{0}{10} \ \Rightarrow\ x = 0
  4. 4

    Check: put x = 0 back into the equation.
