The lines y = 2x + 8 and y = 46 meet at x = 19141618202224354045505560x = 19y = 2x + 8y = 46
The lines y = 2x + 8 and y = 46 meet at x = 19. 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.

    2x+8=462x + 8 = 46
  2. 2

    Subtract 8 from both sides:

    2x+8−8=46−8 ⇒ 2x=382x + 8 - 8 = 46 - 8 \ \Rightarrow\ 2x = 38
  3. 3

    Divide both sides by 2:

    2x2=382 ⇒ x=19\frac{2x}{2} = \frac{38}{2} \ \Rightarrow\ x = 19
  4. 4

    Check: put x = 19 back into the equation.
