Explain it step by step in chatMake a short video of it
The lines y = 6x + 3 and y = 63 meet at x = 10468101214162030405060708090100x = 10y = 6x + 3y = 63
The lines y = 6x + 3 and y = 63 meet at x = 10. 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=636x + 3 = 63
  2. 2

    Subtract 3 from both sides:

    6x+3−3=63−3 ⇒ 6x=606x + 3 - 3 = 63 - 3 \ \Rightarrow\ 6x = 60
  3. 3

    Divide both sides by 6:

    6x6=606 ⇒ x=10\frac{6x}{6} = \frac{60}{6} \ \Rightarrow\ x = 10
  4. 4

    Check: put x = 10 back into the equation.
