Please help me!!

5/4x +1/8x=11/8 +x

The solution is x=

Solve by the elimination method.

4x +5y=5

8x +10y=10

What is the solution of the system.

**Reiny**, Tuesday, April 7, 2009 at 11:24pmfor the first, multiply each term by 8,

easy after that.

for the second, there is an infinite number of solutions.

Notice if you double the first equation, you get exactly the second equation.

So really you are just given the same equation twice.

So, any x and y which satisfies the equation is a solution,

e.g.

x = 0, y = 1

x
