Explain it step by step in chatMake a short video of it
The lines y = 5x + 4 and y = 54 meet at x = 10468101214162030405060708090x = 10y = 5x + 4y = 54
The lines y = 5x + 4 and y = 54 meet at x = 10. 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.

    5x+4=545x + 4 = 54
  2. 2

    Subtract 4 from both sides:

    5x+4−4=54−4 ⇒ 5x=505x + 4 - 4 = 54 - 4 \ \Rightarrow\ 5x = 50
  3. 3

    Divide both sides by 5:

    5x5=505 ⇒ x=10\frac{5x}{5} = \frac{50}{5} \ \Rightarrow\ x = 10
  4. 4

    Check: put x = 10 back into the equation.
