Homework Help: Math

Posted by Amanda on Sunday, May 20, 2007 at 10:33am.

Solve the system by addition or substitution.
3x – 4y = 8
6x – 2y = 10

Please get me on the correct track

for 3x -4y =8
x=4, y=1
for 6x - 2y =10
x= 2, y= 1

Solve one equation for x.

3x = 4y + 8

x = (4y + 8)/3

Insert that value for x in the other equation and solve for y. Once you find the value for y, substitute that value in the same original equation and solve for x. Check by putting both values into the equations.

I hope this helps. Thanks for asking.
