4x - 2y = 0<br> -x - 2y = -25

Fittoniya [83]

Answer:

$x=5,y=10$

Step-by-step explanation:

Given:

$4x - 2y = 0$ equation:1

$-x - 2y = -25$ equation:2

Terminating the equations by subtracting equation:2 from equation:1

$4x - 2y -(-x - 2y)= 0-( -25)\\\\ 4x-2y+x+2y=25\\\\5x=25\\\\x=5$

Putting 'x' in equation :1

$4(5) - 2y = 0\\\\20-2y=0\\\\2y=20\\\\y=10$

$x=5,y=10$

Nimfa-mama [501]

Answer:

Step-by-step explanation:

4.5b + 8.5c = 175

b + c = 22.......b = 22 - c

4.5(22 - c) + 8.5c = 175

99 - 4.5c + 8.5c = 175

-4.5c + 8.5c = 175 - 99

4c = 76

c = 76/4

c = 19......there are 19 cats

b + c = 22

b + 19 = 22

b = 22 - 19

b = 3 <==== there are 3 birds

I believe the answer is 25 because it says that 2)m=5 or it may be 30 because 5times 2 equals 10 and 10plus 20 gives you 30
