The solution of 7x + 7 = 14 is x = 1.

Explain it step by step in chatMake a short video of it
The lines y = 7x + 7 and y = 14 meet at x = 1-4-2246-20204060x = 1y = 7x + 7y = 14
The lines y = 7x + 7 and y = 14 meet at x = 1. 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+7=147x + 7 = 14
  2. 2

    Subtract 7 from both sides:

    7x+7−7=14−7 ⇒ 7x=77x + 7 - 7 = 14 - 7 \ \Rightarrow\ 7x = 7
  3. 3

    Divide both sides by 7:

    7x7=77 ⇒ x=1\frac{7x}{7} = \frac{7}{7} \ \Rightarrow\ x = 1
  4. 4

    Check: put x = 1 back into the equation.

    7⋅1+7=7+7=14✓7\cdot1 + 7 = 7 + 7 = 14 \checkmark
