The lines y = 3x + 2 and y = 50 meet at x = 16. 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.

    3x+2=503x + 2 = 50
  2. 2

    Subtract 2 from both sides:

    3x+2−2=50−2 ⇒ 3x=483x + 2 - 2 = 50 - 2 \ \Rightarrow\ 3x = 48
  3. 3

    Divide both sides by 3:

    3x3=483 ⇒ x=16\frac{3x}{3} = \frac{48}{3} \ \Rightarrow\ x = 16
  4. 4

    Check: put x = 16 back into the equation.
