To get rid of the parantheses we must multiply -4 times anything inside the parantheses.
<em>-4(7x+5)=-160</em>
<em>-28x-20=-160</em>
Add 20 to both sides of the equation.
<em>-28x-20=-160</em>
<em>-28x=-140</em>
Divide both sides by -28
<em>-28x/-28=-140/-28</em>
<em>x=5</em>
<em>Our final answer is 5 </em>
