The lines y = 7x + 10 and y = 94 meet at x = 12. 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.

    7x+10=947x + 10 = 94
  2. 2

    Subtract 10 from both sides:

    7x+10−10=94−10 ⇒ 7x=847x + 10 - 10 = 94 - 10 \ \Rightarrow\ 7x = 84
  3. 3

    Divide both sides by 7:

    7x7=847 ⇒ x=12\frac{7x}{7} = \frac{84}{7} \ \Rightarrow\ x = 12
  4. 4

    Check: put x = 12 back into the equation.
