The solution of 8x + 2 = 34 is x = 4.

Explain it step by step in chatMake a short video of it
The lines y = 8x + 2 and y = 34 meet at x = 4-2246810-2020406080x = 4y = 8x + 2y = 34
The lines y = 8x + 2 and y = 34 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.

    8x+2=348x + 2 = 34
  2. 2

    Subtract 2 from both sides:

    8x+2−2=34−2 ⇒ 8x=328x + 2 - 2 = 34 - 2 \ \Rightarrow\ 8x = 32
  3. 3

    Divide both sides by 8:

    8x8=328 ⇒ x=4\frac{8x}{8} = \frac{32}{8} \ \Rightarrow\ x = 4
  4. 4

    Check: put x = 4 back into the equation.
