Explain it step by step in chatMake a short video of it
The lines y = 12x + 1 and y = 49 meet at x = 4-2246810-2020406080100120x = 4y = 12x + 1y = 49
The lines y = 12x + 1 and y = 49 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+1=4912x + 1 = 49
  2. 2

    Subtract 1 from both sides:

    12x+1−1=49−1 ⇒ 12x=4812x + 1 - 1 = 49 - 1 \ \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.
