Question

slove: 3x-4y=10
5x-3y=2

Answer 1

3x-4y=10 (1)
5x-3y=2 (2)

multiply (1) by -3 and (2) by 4:

-9x+12y=-30
10x-12y=80

add (1) to (2):

x=50

solve either equation for y:

3x-4y=10
y=(3/4)x-5/2=3/4(50)-5/2=70/2=35

so

x=50
y=35

is the solution

Answer 2

thers a slight error on 5th line turing it 8 not 80

Answer 3

Oh man that's not slight. Dang...
