0.75(8 + e) = 2 - 1.25e

0.75(8) = 6

6 + 0.75e = 2 - 1.25e

Add 1.25e on both sides

6 + 2e = 2

Subtract 6 on both sides

2e = -4

Divide the whole thing by 2

e = -2

0.75(8+e)=2-1.25e
0.75(8)+(0.75)(e)=2+-1.25e
6+0.75e=2+-1.25e
0.75e+6=-1.25e+2
0.75e+6+1.25=-1.25e+2+1.25e
2e+6=2
2e+6-6=2-6
2e=-4
2e/2=-4/2
e=-2
