Explain it step by step in chatMake a short video of it
The lines y = 12x + 5 and y = 53 meet at x = 4-2246810-2020406080100120140x = 4y = 12x + 5y = 53
The lines y = 12x + 5 and y = 53 meet at x = 4. 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.

    12x+5=5312x + 5 = 53
  2. 2

    Subtract 5 from both sides:

    12x+5−5=53−5 ⇒ 12x=4812x + 5 - 5 = 53 - 5 \ \Rightarrow\ 12x = 48
  3. 3

    Divide both sides by 12:

    12x12=4812 ⇒ x=4\frac{12x}{12} = \frac{48}{12} \ \Rightarrow\ x = 4
  4. 4

    Check: put x = 4 back into the equation.
