Answer:
i think is c tell me if im right
x+4y=15 2x-y=-15
We have to make x neg.
-2(x) + 4y (-2)= -2(15)
-2x-8y=-30
2x-y=-15
-9y= -45
Solve for y
Y=-45/-9
Y = 5
Substitute your y answer into one original equation to find x .
x+4y=15
X+4(5)=15
X+20=15
X=15-20
X= -5
Answer is (-5,5)
Answer:
t = 2.58333
Step-by-step explanation:
use the distributive property:
200 = 16(6t - 3)
multiply the 16 to each value in the parenthesis:
200 = 96t - 48
now add 48 to both sides:
200 = 96t - 48
+48 + 48
248 = 96t
now divide each side by 96:
248/96 = 96t/96
t = 2.583333
decimal form: 2.5833333
