Explain it step by step in chatMake a short video of it
The lines y = 6x + 5 and y = 23 meet at x = 3-22468-20-10102030405060x = 3y = 6x + 5y = 23
The lines y = 6x + 5 and y = 23 meet at x = 3. 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+5=236x + 5 = 23
  2. 2

    Subtract 5 from both sides:

    6x+5−5=23−5 ⇒ 6x=186x + 5 - 5 = 23 - 5 \ \Rightarrow\ 6x = 18
  3. 3

    Divide both sides by 6:

    6x6=186 ⇒ x=3\frac{6x}{6} = \frac{18}{6} \ \Rightarrow\ x = 3
  4. 4

    Check: put x = 3 back into the equation.
