Explain it step by step in chatMake a short video of it
The lines y = 10x + 2 and y = 32 meet at x = 3-22468-40-2020406080100x = 3y = 10x + 2y = 32
The lines y = 10x + 2 and y = 32 meet at x = 3. 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.

    10x+2=3210x + 2 = 32
  2. 2

    Subtract 2 from both sides:

    10x+2−2=32−2 ⇒ 10x=3010x + 2 - 2 = 32 - 2 \ \Rightarrow\ 10x = 30
  3. 3

    Divide both sides by 10:

    10x10=3010 ⇒ x=3\frac{10x}{10} = \frac{30}{10} \ \Rightarrow\ x = 3
  4. 4

    Check: put x = 3 back into the equation.
