Question

if you help you get a medal and a fan
solve the system of equations:
.5x-.75y=3
-2x+3y=-12

Answer 1

x will always = 1 so now try it but put x as 1

Answer 2

its like sqared 1

Answer 3

Use the elimination method...mutiply the second eq with 25

Answer 4

multiply*

Answer 5

multiply eq 2 by 25 it will become -50x+75y=-180..now add eq 1 and 3 as under..5x-75y=3+(-50x+75y=-180)
+75y and -75y will cancell each other the remaining x=1.7..now putt 1.7 in eq 1 which will give us y=0.07

Answer 6

they are equivalent.. 0.o

Answer 7

.5x-.75y=3
-2x+3y=-12(multiply by 25)

5x-.75y=3
-50x+75y=-300
==========
-45x=-297
x=-297/-45
x=6.6

Answer 8

Now put the value of x in the original eq 1.


5x-.75y=3
5(6.6)-75y=3

Solve it.
