Solve 2x + 10 = 6

The solution of 2x + 10 = 6 is x = -2.

Explain it step by step in chatMake a short video of it
The lines y = 2x + 10 and y = 6 meet at x = -2-8-6-4-224-55101520x = -2y = 2x + 10y = 6
The lines y = 2x + 10 and y = 6 meet at x = -2. 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.

    2x+10=62x + 10 = 6
  2. 2

    Subtract 10 from both sides:

    2x+10−10=6−10 ⇒ 2x=−42x + 10 - 10 = 6 - 10 \ \Rightarrow\ 2x = -4
  3. 3

    Divide both sides by 2:

    2x2=−42 ⇒ x=−2\frac{2x}{2} = \frac{-4}{2} \ \Rightarrow\ x = -2
  4. 4

    Check: put x = -2 back into the equation.
