Explain it step by step in chatMake a short video of it
The lines y = 7x + 4 and y = 95 meet at x = 13810121416186080100120140x = 13y = 7x + 4y = 95
The lines y = 7x + 4 and y = 95 meet at x = 13. 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+4=957x + 4 = 95
  2. 2

    Subtract 4 from both sides:

    7x+4−4=95−4 ⇒ 7x=917x + 4 - 4 = 95 - 4 \ \Rightarrow\ 7x = 91
  3. 3

    Divide both sides by 7:

    7x7=917 ⇒ x=13\frac{7x}{7} = \frac{91}{7} \ \Rightarrow\ x = 13
  4. 4

    Check: put x = 13 back into the equation.
