Explain it step by step in chatMake a short video of it
The lines y = 6x āˆ’ 3 and y = 99 meet at x = 1712141618202260708090100110120130140x = 17y = 6x āˆ’ 3y = 99
The lines y = 6x āˆ’ 3 and y = 99 meet at x = 17. 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 subtraction, then the multiplication.

    6xāˆ’3=996x - 3 = 99
  2. 2

    Add 3 to both sides:

    6xāˆ’3+3=99+3Ā ā‡’Ā 6x=1026x - 3 + 3 = 99 + 3 \ \Rightarrow\ 6x = 102
  3. 3

    Divide both sides by 6:

    6x6=1026Ā ā‡’Ā x=17\frac{6x}{6} = \frac{102}{6} \ \Rightarrow\ x = 17
  4. 4

    Check: put x = 17 back into the equation.
