Explain it step by step in chatMake a short video of it
The lines y = 10x + 3 and y = 63 meet at x = 62468101220406080100120x = 6y = 10x + 3y = 63
The lines y = 10x + 3 and y = 63 meet at x = 6. 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=6310x + 3 = 63
  2. 2

    Subtract 3 from both sides:

    10x+3−3=63−3 ⇒ 10x=6010x + 3 - 3 = 63 - 3 \ \Rightarrow\ 10x = 60
  3. 3

    Divide both sides by 10:

    10x10=6010 ⇒ x=6\frac{10x}{10} = \frac{60}{10} \ \Rightarrow\ x = 6
  4. 4

    Check: put x = 6 back into the equation.
