Full solution

Q. Solve for xx: \newline3x+4=193x+4=19
  1. Isolate variable term: Isolate the term with the variable xx. To do this, we need to get rid of the constant term on the same side as the variable term. We can subtract 44 from both sides of the equation. 3x+4−4=19−43x + 4 - 4 = 19 - 4 3x=153x = 15
  2. Solve for x: Solve for x.\newlineNow that we have isolated the term with xx, we can solve for xx by dividing both sides of the equation by the coefficient of xx, which is 33.\newline3x3=153\frac{3x}{3} = \frac{15}{3}\newlinex=5x = 5
