x =2 y =8
2x + 2y=20
2x=20-2y
x=10-y
Ahora len la otra ecuacion remplazamos x por (10-y)
-2(10-y)-6y=-52
-20+2y-6y=-52
2y-6y= -32 (-52+20= -32)
-4y=-32
-y=-8
y=8 x=10-y x=2
2*2+2*8=20
4+16=20
-2*2-6*8= -52
-4-48= -52
Answer:
D. Multiplication property of equality
Step-by-step explanation:
5 is multiplied to both sides of the equation, resulting to x = -10
Yes that sequence is geometric although it’s negative
It is c because the girls are first and that’s 27 then you do it to the total amount of kids
