Solve 2x + 10 = 2

The solution of 2x + 10 = 2 is x = -4.

Explain it step by step in chatMake a short video of it
The lines y = 2x + 10 and y = 2 meet at x = -4-10-8-6-4-22-10-551015x = -4y = 2x + 10y = 2
The lines y = 2x + 10 and y = 2 meet at x = -4. 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=22x + 10 = 2
  2. 2

    Subtract 10 from both sides:

    2x+10−10=2−10 ⇒ 2x=−82x + 10 - 10 = 2 - 10 \ \Rightarrow\ 2x = -8
  3. 3

    Divide both sides by 2:

    2x2=−82 ⇒ x=−4\frac{2x}{2} = \frac{-8}{2} \ \Rightarrow\ x = -4
  4. 4

    Check: put x = -4 back into the equation.

    2⋅(−4)+10=−8+10=2✓2\cdot(-4) + 10 = -8 + 10 = 2 \checkmark
