solve the system of equations using elimination.

Question

x/2 + y/2= -4

x/5- y/5= 4/5

 

 

how do i solve this step by step?

Answer 1

Step one is to clear fractions. You need to know this technique.

Multiply the first equation by two to kill ofs the denominators (don't forget to multiply the -4 by two, also).

Multiply the second equation by five to kill off all its denominators.

 

At that point you will be on familiar ground with a system of two linear equations, and I trust that you can complete the work. Check your answers on both equations.
