<span>Solve this by substitution:
</span>Solve 5x - 4y = -13 for x:<span><span><span><span>5x </span>− <span>4y </span></span>+ <span>4y </span></span>= -<span>13 + <span>4y </span></span></span>(Add 4y to both sides)
<span><span><u>5x </u></span>= <span><span><u>4y - </u><u>13 </u></span><u> </u> </span></span>(Divide both sides by 5)
5 5
<span>x = <span><span><span><u>4</u></span> y </span>+ -<span><u>13</u><span>
</span></span></span></span> 5 5

Answer:
PQ=6,69 units
Step-by-step explanation:
b/Sin32°=c/Sin72°
PQ/Sin32°=12/Sin72°
PQSin72°=12Sin32°
PQ=12Sin32°/Sin72°
PQ=6.69 units
