The lines y = 3x + 7 and y = 25 meet at x = 62468101251015202530354045x = 6y = 3x + 7y = 25
The lines y = 3x + 7 and y = 25 meet at x = 6. 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.

    3x+7=253x + 7 = 25
  2. 2

    Subtract 7 from both sides:

    3x+7−7=25−7 ⇒ 3x=183x + 7 - 7 = 25 - 7 \ \Rightarrow\ 3x = 18
  3. 3

    Divide both sides by 3:

    3x3=183 ⇒ x=6\frac{3x}{3} = \frac{18}{3} \ \Rightarrow\ x = 6
  4. 4

    Check: put x = 6 back into the equation.
