I HOPE THIS HELPED IF WRONG IM SORRY
Simplify both sides of the equation.
<span><span><span>(−7.8)(x)</span>+<span>(−7.8)(6.5)</span></span>=−25.74 </span> <span><span><span>−7.8x+</span>−50.7</span>=−25.74 -> </span>−7.8x−50.7=−25.74
<span>Add 50.7 to both sides.
</span><span><span>−7.8x−50.7</span>+50.7</span>=−25.74+50.7 -> −7.8x = <span>24.96
</span><span>Divide both sides by -7.8.
</span><span>−7.8x /−7.8 </span>= <span>24.96/<span>−<span>7.8
</span></span></span><span>And as a decimal
X= </span><span>−3.2
Hope this helped. (got taken off because I did the steps? oo well)</span>
Answer:
Step-by-step explanation:
