Step-by-step explanation:
The answer is 0.64,65,2/3,7/10 how I got it is because you need to turn all the numbers into decimals
7/10=.7
2/3=0.666666.....
and the others one are already in decimal form
If we are eliminating x, we would multiply the 2nd equation by -5
5x + 18y = 23
x + 3y = 2....multiply by -5
-----------------
5x + 18y = 23
-5x - 15y = - 10 (result of multiplying by -5)
----------------add
0 + 3y = 13.....bye-bye x :)
