One possiablilty is 33%, .33, 1/3. <span />
Subtract 39 from both sides
-7x = -4 - 39
Simplify -4 - 39 to -43
-7x = -43
Divide both sides by -7
x = -43/-7
Two negative make a positive
<u>x = 43/7</u>
<em>For the second equation;</em>
Simplify brackets
7x + 7 = 4
Subtract 7 from both sides
7x = 4 - 7
Simplify 4 - 7 to -3
7x = -3
Divide both sides by 7
<u>x = -3/7</u>
