Explain it step by step in chatMake a short video of it
The lines y = 4x + 3 and y = 23 meet at x = 52468101020304050x = 5y = 4x + 3y = 23
The lines y = 4x + 3 and y = 23 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.

    4x+3=234x + 3 = 23
  2. 2

    Subtract 3 from both sides:

    4x+3−3=23−3 ⇒ 4x=204x + 3 - 3 = 23 - 3 \ \Rightarrow\ 4x = 20
  3. 3

    Divide both sides by 4:

    4x4=204 ⇒ x=5\frac{4x}{4} = \frac{20}{4} \ \Rightarrow\ x = 5
  4. 4

    Check: put x = 5 back into the equation.
