Explain it step by step in chatMake a short video of it
The lines y = 3x + 5 and y = 14 meet at x = 3-22468-55101520253035x = 3y = 3x + 5y = 14
The lines y = 3x + 5 and y = 14 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.

    3x+5=143x + 5 = 14
  2. 2

    Subtract 5 from both sides:

    3x+5−5=14−5 ⇒ 3x=93x + 5 - 5 = 14 - 5 \ \Rightarrow\ 3x = 9
  3. 3

    Divide both sides by 3:

    3x3=93 ⇒ x=3\frac{3x}{3} = \frac{9}{3} \ \Rightarrow\ x = 3
  4. 4

    Check: put x = 3 back into the equation.
