Answer: x = 75

Step-by-step explanation:

The expression we have is:


(2)/(3)(x-9)=(1)/(3)x+19

to solve for x.

Step 1: Use the distributive property (multiply the numbers outside the parenthesis by the numbers inside the parenthesis)


(2)/(3)x-(18)/(3)=(1)/(3)x+19

We can simplify 18/3 to 6:


(2)/(3)x-6=(1)/(3)x+19

Step 2: Move all of the terms that contain x to the left and all of the independent terms to the right. (Note* when we move a term to the opposite side of the equation it does that with the opposite operation in this case opposite sign)


(2)/(3)x-(1)/(3)x=19+6

Step 3: Combine like terms


(1)/(3)x=25

step 4: Multiply both sides of the equation by 3


\begin{gathered} 3((1)/(3)x)=3\cdot25 \\ x=75 \end{gathered}

Answer: x=75
