Answer:
<em>4</em><em>*</em><em>5x-7</em><em>=</em><em>20</em>
4*5(-7)-7=20
20(-7)-7=20
-140-7=20
-140=20+7
-140=27
=27+140
<u>=</u><u>167</u>
<em>-</em><em>3x</em><em>+</em><em>7</em><em>=</em><em>28</em>
-3(6)+7=28
-3(6)=28-7
-18=21
=21+18
<u>=</u><u>39</u>
<em>2x</em><em>+</em><em>3</em><em>=-7</em>
2(-5)+3=-7
2(-5)=-7-3
-10=-10
=-10+10
<u>=</u><u>0</u>
