The solution of 9x + 3 = 48 is x = 5.

Explain it step by step in chatMake a short video of it
The lines y = 9x + 3 and y = 48 meet at x = 524681020406080100x = 5y = 9x + 3y = 48
The lines y = 9x + 3 and y = 48 meet at x = 5. 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.

    9x+3=489x + 3 = 48
  2. 2

    Subtract 3 from both sides:

    9x+3−3=48−3 ⇒ 9x=459x + 3 - 3 = 48 - 3 \ \Rightarrow\ 9x = 45
  3. 3

    Divide both sides by 9:

    9x9=459 ⇒ x=5\frac{9x}{9} = \frac{45}{9} \ \Rightarrow\ x = 5
  4. 4

    Check: put x = 5 back into the equation.
