Explain it step by step in chatMake a short video of it
The lines y = 8x + 3 and y = 59 meet at x = 72468101220406080100x = 7y = 8x + 3y = 59
The lines y = 8x + 3 and y = 59 meet at x = 7. 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+3=598x + 3 = 59
  2. 2

    Subtract 3 from both sides:

    8x+3−3=59−3 ⇒ 8x=568x + 3 - 3 = 59 - 3 \ \Rightarrow\ 8x = 56
  3. 3

    Divide both sides by 8:

    8x8=568 ⇒ x=7\frac{8x}{8} = \frac{56}{8} \ \Rightarrow\ x = 7
  4. 4

    Check: put x = 7 back into the equation.
