Question

Solve the following systems of linear equations. [3x+7y= -4 and 2x+5y= -3]

Answer 1

Answer: it's actually (4/17, -8/17)

Answer 2

eliminate
multiply first equatin by -2
mulitply second by 3 and add them

-6x-14y=8
6x+15y=-6
add them
y=2
sub

3x+7(2)=-4
3x+14=-4
minus 14
3x=-18
divide 3
x=-6
(-6,2)
