 solve for x x/9−5=5<br><br>x=​
gregori [183]

Answer:

<u>x=90</u>

Step-by-step explanation:

<em />

<em>Let's solve your equation step-by-step.</em>

x/9−5=5

<em>Step 1: Simplify both sides of the equation.</em>

x/9−5=5

1/9x+−5=5

1/9x−5=5

<em>Step 2: Add 5 to both sides.</em>

1/9x−5+5=5+5

1/9x=10

<em>Step 3: Multiply both sides by 9.</em>

9*(1/9x)=(9)*(10)

x=90

Answer:

<u>x=90</u>
