Question

Is (-2, -5) a solution of the system, 3x + 2y = 4 and 2x - 5y = -29?


yes

no

Answer 1

I would check to see of x=-2 and y=-5 "works" in both equations
if it does, then yes
if it fails for either, then no

Answer 2

for example, in
3x + 2y = 4
replace the x with -2 and y with -5
3*-2 + 2*-5 = 4 ?
(remember 3x is short for 3 times x , or in this case 3 times -2. ditto for y)

Answer 3

what is 3 * -2 ?
