The solution of 5x + 14 = 4 is x = -2.

Explain it step by step in chatMake a short video of it
The lines y = 5x + 14 and y = 4 meet at x = -2-8-6-4-224-30-20-1010203040x = -2y = 5x + 14y = 4
The lines y = 5x + 14 and y = 4 meet at x = -2. 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.

    5x+14=45x + 14 = 4
  2. 2

    Subtract 14 from both sides:

    5x+14−14=4−14 ⇒ 5x=−105x + 14 - 14 = 4 - 14 \ \Rightarrow\ 5x = -10
  3. 3

    Divide both sides by 5:

    5x5=−105 ⇒ x=−2\frac{5x}{5} = \frac{-10}{5} \ \Rightarrow\ x = -2
  4. 4

    Check: put x = -2 back into the equation.

    5⋅(−2)+14=−10+14=4✓5\cdot(-2) + 14 = -10 + 14 = 4 \checkmark
