Explain it step by step in chatMake a short video of it
The lines y = 7x + 1 and y = 36 meet at x = 524681020406080x = 5y = 7x + 1y = 36
The lines y = 7x + 1 and y = 36 meet at x = 5. 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=367x + 1 = 36
  2. 2

    Subtract 1 from both sides:

    7x+1−1=36−1 ⇒ 7x=357x + 1 - 1 = 36 - 1 \ \Rightarrow\ 7x = 35
  3. 3

    Divide both sides by 7:

    7x7=357 ⇒ x=5\frac{7x}{7} = \frac{35}{7} \ \Rightarrow\ x = 5
  4. 4

    Check: put x = 5 back into the equation.

    7⋅5+1=35+1=36✓7\cdot5 + 1 = 35 + 1 = 36 \checkmark
