Solve each equation.<br> 1. 25 - 3x = 40<br> 2. } (x – 10) = -4
nordsb [41]

Step-by-step explanation:

For no 1

<em>2</em><em>5</em><em> </em><em>-</em><em> </em><em>3x </em><em>=</em><em> </em><em>4</em><em>0</em><em> </em>

<em>-</em><em> </em><em>3x </em><em>=</em><em> </em><em>4</em><em>0</em><em> </em><em>-</em><em> </em><em>2</em><em>5</em><em> </em>

<em>-</em><em> </em><em>3x </em><em>=</em><em> </em><em>1</em><em>5</em><em> </em>

<em> </em><em>-</em><em> </em><em>x </em><em>=</em><em> </em><em>1</em><em>5</em><em> </em><em>/</em><em> </em><em>3</em>

<em>Therefore </em><em> </em><em>x </em><em>=</em><em> </em><em>-</em><em> </em><em>5</em><em> </em>

<em>Now </em><em>for </em><em>no. </em><em> </em><em>2</em>

<em>1</em><em>/</em><em>3</em><em> </em><em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>1</em><em>0</em><em>)</em><em> </em><em>=</em><em> </em><em>-</em><em> </em><em>4</em><em> </em>

<em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>1</em><em>0</em><em> </em><em>)</em><em> </em><em>=</em><em> </em><em>-</em><em> </em><em>1</em><em>2</em><em> </em>

<em>x </em><em>=</em><em> </em><em>-</em><em> </em><em>1</em><em>2</em><em> </em><em>+</em><em> </em><em>1</em><em>0</em>

<em>Therefore </em><em> </em><em>x </em><em>=</em><em> </em><em>-</em><em> </em><em>2</em><em> </em>

<em>Hope </em><em>it </em><em>will </em><em>help </em><em>:</em><em>)</em>
