We just substitute in -12 for x in each one and see if it's true

2(-12)+6 = -24 + 6 = -18, not 30, NOPE

-0.25(-12) - 1 = 3-1 = 2, that worked, CHECK ME

-12 - 8 = -20, CHECK ME

-35(-12) +2 = 422, not -515, NOPE

3(-12+25)=3(13)=39, CHECK ME

X+y = -16<br> —3х – у = 30

lys-0071 [83]

Answer:

x = -7, y = -9

Step-by-step explanation:

The coefficient (the number before) the y is the same but the signs are opposite so add the equations together:

x-3x+y-y=-16+30

-2x=14

x=-7

y=-16-x=-16--7=-9
