so would the new eqaution be...
We know that y = x + 8.
So if x + y = 10, then x + x + 8 = 10.
but what about the y?ANd what do I do afetr that?
If you know what x equals, then you can calculate what y equals.
Once you've solved for x and y, you are done.
I need help bcause I don't understand and tommorrow I have test.
Use the Substitution method to solve the system of equations.
x + y = 10
y = x + 8
now put x=1 into either of the original equations, and solve for y.
x + y=10
1+y=10 solve for y.
thanx!can you help me with this one:
3x + y = 5
4x - 7y = -10
solve for y in the first equation...that is in terms of x. Then put this expression into the second equation..
4x-7(expresson for y here)=-10
then solve for x.
Put only one problem per thread please. Start a new thread if you have a new problem, it makes life simpler.

16x2 − 9y2
16x2 + 24xy + 9y2
16x2 + 9y2
