The lines y = 2x + 5 and y = 35 meet at x = 151012141618202530354045x = 15y = 2x + 5y = 35
The lines y = 2x + 5 and y = 35 meet at x = 15. 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.

    2x+5=352x + 5 = 35
  2. 2

    Subtract 5 from both sides:

    2x+5−5=35−5 ⇒ 2x=302x + 5 - 5 = 35 - 5 \ \Rightarrow\ 2x = 30
  3. 3

    Divide both sides by 2:

    2x2=302 ⇒ x=15\frac{2x}{2} = \frac{30}{2} \ \Rightarrow\ x = 15
  4. 4

    Check: put x = 15 back into the equation.
