The lines y = 8x + 5 and y = 157 meet at x = 19. 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+5=1578x + 5 = 157
  2. 2

    Subtract 5 from both sides:

    8x+5−5=157−5 ⇒ 8x=1528x + 5 - 5 = 157 - 5 \ \Rightarrow\ 8x = 152
  3. 3

    Divide both sides by 8:

    8x8=1528 ⇒ x=19\frac{8x}{8} = \frac{152}{8} \ \Rightarrow\ x = 19
  4. 4

    Check: put x = 19 back into the equation.
