You flip the second fraction and you multiply. 1 and 2/5 or 1.4
10/15 =6/9
6*15=90
90/9=10, this is how I found 10,
also, is you simplify both, you get 2/3
Answer:
x=1.875 y=-0.875
Step-by-step explanation:
10x-3y=3 10x-3y=3
3(2x+y)=(9)3 +<u>6x+3y=27</u>
1/16(16x)=(30)1/16 = x=1.875
10x-3y=3 10x-3y=3
-5(2x+y)=(9)-5 -<u>10x-5y=4 </u>
1/-8(-8y)=(7)1/-8 = y=-0.875
