Solve 8x + 1 = 17

The solution of 8x + 1 = 17 is x = 2.

Explain it step by step in chatMake a short video of it
The lines y = 8x + 1 and y = 17 meet at x = 2-4-22468-40-20204060x = 2y = 8x + 1y = 17
The lines y = 8x + 1 and y = 17 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.

    8x+1=178x + 1 = 17
  2. 2

    Subtract 1 from both sides:

    8x+1−1=17−1 ⇒ 8x=168x + 1 - 1 = 17 - 1 \ \Rightarrow\ 8x = 16
  3. 3

    Divide both sides by 8:

    8x8=168 ⇒ x=2\frac{8x}{8} = \frac{16}{8} \ \Rightarrow\ x = 2
  4. 4

    Check: put x = 2 back into the equation.

    8⋅2+1=16+1=17✓8\cdot2 + 1 = 16 + 1 = 17 \checkmark
