Given function and value: Write down the given function and the value of g(x) we are trying to find.We have the function g(x)=2x+9 and we want to find the value of x when g(x)=15.
Equation setup: Set up the equation to solve for x.We need to solve the equation 2x+9=15.
Isolating the term with x: Subtract 9 from both sides of the equation to isolate the term with x.2x+9−9=15−9This simplifies to 2x=6.
Solving for x: Divide both sides of the equation by 2 to solve for x.22x=26This simplifies to x=3.
