Question

Solve the system 3x - 5y = 8 and 4x - 7y = 10.

Answer 1

solve one of the equations for x and then plug that into the other equation

Answer 2

x = (8/3) + (5/3)y

plug that into

4((8/3) + (5/3)y) - 7y =10

Answer 3

yeah...
X=6
Y=2

Answer 4

3x - 5y = 8
4x-7y = 10

3x - 8 = 5y
4x - 10 = 7y

y = (3x-8)/5
y = (4x-10)/7

y = y

7(3x-8) = 5(4x-10)
21x - 56 = 20x - 50
21x - 20 = 56 - 50
x = 6
y = 2

Answer 5

Thanks, but I think you're supposed to write it in the form of exponents.

Answer 6

Oh, nevermind. I figured it out. Thanks!

Answer 7

You mean x,y = (6,2)
