Explain it step by step in chatMake a short video of it
The lines y = 7x + 6 and y = 48 meet at x = 62468101220406080x = 6y = 7x + 6y = 48
The lines y = 7x + 6 and y = 48 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.

    7x+6=487x + 6 = 48
  2. 2

    Subtract 6 from both sides:

    7x+6−6=48−6 ⇒ 7x=427x + 6 - 6 = 48 - 6 \ \Rightarrow\ 7x = 42
  3. 3

    Divide both sides by 7:

    7x7=427 ⇒ x=6\frac{7x}{7} = \frac{42}{7} \ \Rightarrow\ x = 6
  4. 4

    Check: put x = 6 back into the equation.
