Explain it step by step in chatMake a short video of it
The lines y = 4x + 11 and y = 39 meet at x = 7246810122030405060x = 7y = 4x + 11y = 39
The lines y = 4x + 11 and y = 39 meet at x = 7. 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+11=394x + 11 = 39
  2. 2

    Subtract 11 from both sides:

    4x+11−11=39−11 ⇒ 4x=284x + 11 - 11 = 39 - 11 \ \Rightarrow\ 4x = 28
  3. 3

    Divide both sides by 4:

    4x4=284 ⇒ x=7\frac{4x}{4} = \frac{28}{4} \ \Rightarrow\ x = 7
  4. 4

    Check: put x = 7 back into the equation.
