Question

-2x + 5y = 11
6x - 7y = 23
solve for x and y. Please help.

Answer 1

Answer:

X = 12

Y = 7

Hope this helps you

Answer 2

5y = 11+(-2x)

y = (11-2x)/5 ----- equation 1

6x - 7y = 23 -----eq.2

put value of y in eq. 2

6x- 7[(11- 2x)/5] = 23

NOW YOU CAN SOLVE THE EQUATION

AND CAN GIND FIRST x AND THEN y.

at last X=12

Y= 7

I HOPE ITS HELPFUL.
