Answer:
x=-19
y=55
Step-by-step explanation:
y=-3x-2.
5x+2y=15
substitute y into 5x+2y =15
5x +2 (-3x-2) = 15
distribute
5x -6x-4 = 15
combine like terms
-x-4 =15
add 4 to each side
-x-4+4 = 15+4
-x=19
multiply by -1
x = -19
now lets find y
y= -3x-2
y = -3(-19) -2
y = 57-2
y =55

Answer:
plz mark brailyst the answer is 378
Step-by-step explanation:
each yard is 4.5 feet
and 4.5 times 84 is 378
Y + x = -2
y = 1/2x + 7
substitue...
1/2x + 7 + x = -2
1.5x = -9
x = -6
y + (-6) = -2
y-6=-2
y=4
so your final answers are
x = -6 , y = 4
