Answer: 92
Step-by-step explanation:
So 12 +80 = 4(3 + 20) = 92
Answer:
y = 3
x = 2
Step-by-step explanation:
-5x + 4y = 2
9x - 4y = 6
Sum both eq.
-5x + 9x = 4x
+4y - 4y = 0
2 + 6 = 8
then:
4x + 0 = 8
4x = 8
x = 8/4
x = 2
from the first eq.
-5x + 4y = 2
-5*2 + 4y = 2
-10 + 4y = 2
4y = 2 + 10
4y = 12
y = 12/4
y = 3
Check:
from the second eq.
9x - 4y = 6
9*2 - 4*3 = 6
18 - 12 = 6
2+x=2x-15
>> 2+15=2x-x
>> 17 = x
So the answer is <u>17</u>
Answer:
24+24x I believe is the answer. Good luck on your test :)
