Solve 2x + 3 = 1

The solution of 2x + 3 = 1 is x = -1.

Explain it step by step in chatMake a short video of it
The lines y = 2x + 3 and y = 1 meet at x = -1-6-4-224-10-551015x = -1y = 2x + 3y = 1
The lines y = 2x + 3 and y = 1 meet at x = -1. 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+3=12x + 3 = 1
  2. 2

    Subtract 3 from both sides:

    2x+3−3=1−3 ⇒ 2x=−22x + 3 - 3 = 1 - 3 \ \Rightarrow\ 2x = -2
  3. 3

    Divide both sides by 2:

    2x2=−22 ⇒ x=−1\frac{2x}{2} = \frac{-2}{2} \ \Rightarrow\ x = -1
  4. 4

    Check: put x = -1 back into the equation.
