Question

3x + 4y =8
-2x + 5y = 3

i got no solution. am i right or wrong? if wrong what is the correct answer?

Answer 1

system of equations problem ~

Answer 2

well, i do get a solution

Answer 3

what'd you get?

Answer 4

3x + 4y =8
-2x + 5y = 3

multiply the top equation by 2
multiply the bottom equation by 3
this allows the x values to cancel out since the top is +6x and the bottom is -6x

2(3x+4y=8)
3(-2x+5y=3)

6x+8y=16
-6x+15y=9

add vertically.
8y+15y=16+9

23y=25

y = 25/23

plug back into either equation to find x.
