Explain it step by step in chatMake a short video of it
The lines y = 2x + 3 and y = 37 meet at x = 17121416182022253035404550x = 17y = 2x + 3y = 37
The lines y = 2x + 3 and y = 37 meet at x = 17. 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+3=372x + 3 = 37
  2. 2

    Subtract 3 from both sides:

    2x+3−3=37−3 ⇒ 2x=342x + 3 - 3 = 37 - 3 \ \Rightarrow\ 2x = 34
  3. 3

    Divide both sides by 2:

    2x2=342 ⇒ x=17\frac{2x}{2} = \frac{34}{2} \ \Rightarrow\ x = 17
  4. 4

    Check: put x = 17 back into the equation.
