What is the answer to -22/9r = 11/9

astra-53 [7]

Answer:

2

Step-by-step explanation:

<em>for </em><em>this </em><em>question</em><em> </em><em>you've </em><em>to </em><em>cross </em><em>multiply</em>

<em>-</em><em>2</em><em>2</em><em>/</em><em>9</em><em>r</em><em>=</em><em>1</em><em>1</em><em>/</em><em>9</em>

<em>9</em><em>9</em><em>r</em><em>=</em><em>-</em><em>1</em><em>9</em><em>8</em>

<em>then </em><em>you </em><em>divide</em><em> both</em><em> sides</em><em> by</em><em> </em><em>9</em><em>9</em><em> </em><em>inorder </em><em>to </em><em>remain </em><em>with </em><em>r </em><em>on </em><em>one </em><em>side</em>

<em>9</em><em>9</em><em>r</em><em>/</em><em>9</em><em>9</em><em>=</em><em>1</em><em>9</em><em>8</em><em>/</em><em>9</em><em>9</em>

<em>r=</em><em>2</em>

<em>I </em><em>hope </em><em>this </em><em>helps</em>
