Answer:
<em><u>x = -0.5</u></em><em> </em>
Step-by-step explanation:
<em>You need to combine like terms</em>
x * 2 + 5x = -6
<em>Add x to 5x</em>
6x * 2 = -6
<em>Divide 2 from both sides</em>
6x = -3
<em>Divide 6 from both sides to get x alone</em>
x = -0.5

D=vt, distance is equal to velocity times time.
4v+3(v+3)=149 perform indicated multiplication
4v+3v+9=149 combine like terms on left side
7v+9=149 subtract 9 from both sides
7v=140 divide both sides by 7
v=20
So the ship traveled at a speed of 20 mph when heading east.
