Answer:
y = 1
x = -3
Step-by-step explanation:
9x + 2y = 3
-x - y = -12 (multiply second equation with 9)
9x + 2y = 3
-9x - 9y = - 108 (add these to up)
-7y = -105
y = 15 use this to find x
9x + 2y ➡ 9x + 30 = 3 ➡ 9x = -27 ➡ x = -3
Hey so the answer is D because when you subtract you would get the other side of the problem
Answer:
867 seats
Step-by-step explanation:
71094 ÷ 82 = 867
Hope that helps.
The answer would be:
Fraction: 27/32
Decimal: 0.84375
X = -30
First combine like terms (0.02x - 0.01x = 0.01x) (-4 - 2 = -6)
0.01x - 6 = -6.3
Then add 6 (-6 + 6 = 0) (-6.3 + 6 = -0.3)
0.01x = -0.3
Then divide by 0.01 to find what x is alone (0.01x ÷ 0.01 = x) (-0.3 ÷ 0.01 = -30)
x=-30
