PROBLEM #1
3X-5Y=10
7X+2Y=37
PROBLEM #2
4X-5Y=3
-12X+15Y=-9
PROBLEM #3
0.5X-0.2Y=2
1.5X+0.4Y=1
HOW DO YOU GRAPH THIS PROBLEM
Y= 2.3X-7
Y= -0.6X+4
Answer : Problem#1 7(3x-5y)=(10)7 3(7x+2y)=(37)3 =21x-15y=70 =21x+6y=111 then you eliminate two equations =0x-21y= -21 ans: y=1 Problem#2 -3(4x-5y)=3.-3=-12x+15y= -9 and -12x+15y= -9 then you eliminate= 0x+0y=0 ans:y=0 P[roblem#3 3(0.5x-0.2y)=2.(3 )= 1.5x-0.6y=6 and 1.5x+0.4y=1 then you eliminate ans: y= -5 Problem#4 don't you have a graphing calculator? Well, i hope i helped... More from Yahoo Answers
