Explain it step by step in chatMake a short video of it
The lines y = 3x + 14 and y = 35 meet at x = 724681012152025303540455055x = 7y = 3x + 14y = 35
The lines y = 3x + 14 and y = 35 meet at x = 7. 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=353x + 14 = 35
  2. 2

    Subtract 14 from both sides:

    3x+14−14=35−14 ⇒ 3x=213x + 14 - 14 = 35 - 14 \ \Rightarrow\ 3x = 21
  3. 3

    Divide both sides by 3:

    3x3=213 ⇒ x=7\frac{3x}{3} = \frac{21}{3} \ \Rightarrow\ x = 7
  4. 4

    Check: put x = 7 back into the equation.
