Explain it step by step in chatMake a short video of it
The lines y = 3x + 14 and y = 29 meet at x = 5246810101520253035404550x = 5y = 3x + 14y = 29
The lines y = 3x + 14 and y = 29 meet at x = 5. 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+14=293x + 14 = 29
  2. 2

    Subtract 14 from both sides:

    3x+14−14=29−14 ⇒ 3x=153x + 14 - 14 = 29 - 14 \ \Rightarrow\ 3x = 15
  3. 3

    Divide both sides by 3:

    3x3=153 ⇒ x=5\frac{3x}{3} = \frac{15}{3} \ \Rightarrow\ x = 5
  4. 4

    Check: put x = 5 back into the equation.
