From X + Y = 4 
<span>Y = 4 - X </span>
<span>Substituite this for Y in 2X - Y = 2 to get </span>
<span>2X -(4 - X ) = 2 </span>
<span>2X -4 +X = 2 </span>
<span>3X = 6 </span>
<span>X = 2 </span>
<span>Now return to X + Y = 4 </span>
<span>Knowing X = 2, </span>
<span>2 + Y = 4 </span>
<span>Y = 4 - 2 </span>
<span>Y = 2 </span>
<span>The solution is (X,Y) = (2,2) </span>
<span>This is quadrant I </span>

An amount was shared in the ratio 8:6:9:14:12.The largest share was56.What was the total amount shared?
lutik1710 [3]

Answer:

196

Step-by-step explanation:

Since the largest share was 56 and the largest ratio is 14, then

56 ÷ 14 = 4 ← value of 1 part of the share, thus

8 parts = 8 × 4 = 32

6 parts = 6 × 4 = 24

9 parts = 9 × 4 = 36

14 parts = 14 × 4 = 56

12 parts = 12 × 4 = 48

Total the amounts

total = 32 + 24 + 36 + 56 + 48 = 196
