Yes, it’s a solution. First you plug in -2 for x and -4 for y. 5(-2) is -10 and -2(-4) is positive 8. Add -10 to 8 and you’ll get -2 which is what you should get if the ordered pair is a solution. Hope this helps

Answer:
x=19º
x+9=28º
7x=133º
Step-by-step explanation:
x+9+x+7x=180
9x+9=180
9x=180-9
9x=171
x=19
Answer:
A) x = y+25
B) 35 minutes
C) 35 ≠85
Step-by-step explanation:
A)
As we know
X = number of minutes Eric plays basketball
Y = Number of minutes he plays volleyball
x+y= 95
x = y+25
B)
We will replace
x=y+25 in the first equation and we will get (y+25) + y =95
On solving,
y+25+y =95
25+2y=95
2y=95-25
2y=70
y = 70/2
y = 35 minutes
C) X = 35
x+y= 95
35+y =95
y= 95-35
y = 60 minutes
Substituting value of Y as 60 , we get
x = y+25
35 = 60+25
35 ≠85
