Solve 6x + 4 = 64

The solution of 6x + 4 = 64 is x = 10.

The lines y = 6x + 4 and y = 64 meet at x = 104681012141630405060708090100x = 10y = 6x + 4y = 64
The lines y = 6x + 4 and y = 64 meet at x = 10. 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.

    6x+4=646x + 4 = 64
  2. 2

    Subtract 4 from both sides:

    6x+4−4=64−4 ⇒ 6x=606x + 4 - 4 = 64 - 4 \ \Rightarrow\ 6x = 60
  3. 3

    Divide both sides by 6:

    6x6=606 ⇒ x=10\frac{6x}{6} = \frac{60}{6} \ \Rightarrow\ x = 10
  4. 4

    Check: put x = 10 back into the equation.
