Explain it step by step in chatMake a short video of it
The lines y = 5x + 3 and y = 58 meet at x = 11681012141630405060708090x = 11y = 5x + 3y = 58
The lines y = 5x + 3 and y = 58 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.

    5x+3=585x + 3 = 58
  2. 2

    Subtract 3 from both sides:

    5x+3−3=58−3 ⇒ 5x=555x + 3 - 3 = 58 - 3 \ \Rightarrow\ 5x = 55
  3. 3

    Divide both sides by 5:

    5x5=555 ⇒ x=11\frac{5x}{5} = \frac{55}{5} \ \Rightarrow\ x = 11
  4. 4

    Check: put x = 11 back into the equation.
