Answer:

The choices are:

"add -9"

"add -5"

"add -2x"

the correct answer is "add -9"

I used the answer myself and it is correct!

Step-by-step explanation:


calculista

we have

\(5-3x=2x+9\)

Solve for x

Step 1

Add \(3x\) both sides

\(5-3x+3x=2x+9+3x\)

\(5=5x+9\)

Step 2

Add \(-9\) both sides

\(5-9=5x+9-9\)

\(-4=5x\)

Step 3

Divide by \(5\) both sides

\(-4/5=5x/5\)

\(-4/5=x\)

The value of x is equal to \(-4/5\)

therefore

the answer is the option A

Add \(-9\)
