Explain it step by step in chatMake a short video of it
The lines y = 2x + 1 and y = 37 meet at x = 1812141618202224253035404550x = 18y = 2x + 1y = 37
The lines y = 2x + 1 and y = 37 meet at x = 18. 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.

    2x+1=372x + 1 = 37
  2. 2

    Subtract 1 from both sides:

    2x+1−1=37−1 ⇒ 2x=362x + 1 - 1 = 37 - 1 \ \Rightarrow\ 2x = 36
  3. 3

    Divide both sides by 2:

    2x2=362 ⇒ x=18\frac{2x}{2} = \frac{36}{2} \ \Rightarrow\ x = 18
  4. 4

    Check: put x = 18 back into the equation.
