Solve 4x + 9 = 53

The solution of 4x + 9 = 53 is x = 11.

The lines y = 4x + 9 and y = 53 meet at x = 116810121416304050607080x = 11y = 4x + 9y = 53
The lines y = 4x + 9 and y = 53 meet at x = 11. 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.

    4x+9=534x + 9 = 53
  2. 2

    Subtract 9 from both sides:

    4x+9−9=53−9 ⇒ 4x=444x + 9 - 9 = 53 - 9 \ \Rightarrow\ 4x = 44
  3. 3

    Divide both sides by 4:

    4x4=444 ⇒ x=11\frac{4x}{4} = \frac{44}{4} \ \Rightarrow\ x = 11
  4. 4

    Check: put x = 11 back into the equation.
