Solve 7x + 1 = 50

The solution of 7x + 1 = 50 is x = 7.

The lines y = 7x + 1 and y = 50 meet at x = 72468101220406080100x = 7y = 7x + 1y = 50
The lines y = 7x + 1 and y = 50 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.

    7x+1=507x + 1 = 50
  2. 2

    Subtract 1 from both sides:

    7x+1−1=50−1 ⇒ 7x=497x + 1 - 1 = 50 - 1 \ \Rightarrow\ 7x = 49
  3. 3

    Divide both sides by 7:

    7x7=497 ⇒ x=7\frac{7x}{7} = \frac{49}{7} \ \Rightarrow\ x = 7
  4. 4

    Check: put x = 7 back into the equation.
