Question

What is the solution of the system of equations?
y = –2x + 5
–5y = 10x + 20

Answer 1

This is simple First find the value of x from eq1 in terms of y...and then put in eq 2 for finding y and then put the value of y in any equation to find x..

Answer 2

i dont understand ..

Answer 3

shebadd..
on dividing the second equation with 5 would give u
–y = 2x + 4
taking y to the Left Hand side and The other terms to the Right Hand Side
you get
y = -2x - 4

now equate it with the first equation (y = –2x + 5)

Answer 4

so what do u get ?

Answer 5
