Solve 7x + 2 = 2

The solution of 7x + 2 = 2 is x = 0.

Explain it step by step in chatMake a short video of it
The lines y = 7x + 2 and y = 2 meet at x = 0-6-4-2246-40-202040x = 0y = 7x + 2y = 2
The lines y = 7x + 2 and y = 2 meet at x = 0. 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.

    7x+2=27x + 2 = 2
  2. 2

    Subtract 2 from both sides:

    7x+2−2=2−2 ⇒ 7x=07x + 2 - 2 = 2 - 2 \ \Rightarrow\ 7x = 0
  3. 3

    Divide both sides by 7:

    7x7=07 ⇒ x=0\frac{7x}{7} = \frac{0}{7} \ \Rightarrow\ x = 0
  4. 4

    Check: put x = 0 back into the equation.
