Question 282267
7x-4y=-3...Equation A
2x+5y=-7...Equation B

7x - 4y = -3

-4y = -7x - 3

y = (7/4)x + 3/4

Plug this into Equation B to find x.

2x + 5((7/4)x + 3/4) = -7

2x + (35/4)x + 15/4 = -7

2x(4) + 4[(35/4)x + 15/4] = -7(4)

8x + 35x + 3 = -28

43x = -28 - 3

43x = -31

x = -31/43

==================================

Now, plug this value for x into either equations above to find y.

I will use Equation A but you can also use B.

7(-31/43) - 4y = -3

-217/43 - 4y = -3

-4y = -3 + 217/43

y = (-3 + 217/43)/-4

y = -22/43

SOLUTION POINT: (-31/43, -22/43)....This is the answer.

The point (1,1) is not the answer.
