Answer:
X=3, y=-6
Step-by-step explanation:
7x+4y=-3 equation 1
-7x-5y=9 equation 2
-y=6. Add above two equations
Y=-6
solve for x by inputting y value into either equation.
7x+4(-6)=-3
7x-24=-3
7x=21
x=3
check answer by inputting x and y values into either equation
-7x-5y=9
-7(3)-5(-6)=9
–21+30=9
9=9
Answer:
x+3 > 21
the is a line under the greater than symbol
Step-by-step explanation:
Ok.
So an hour contains 60 minutes.
The fraction is therefore,
Hope this helps.
r3t40
9 is added to both sides of the equation then you would combine like terms
80-30=50 your answer would be 50
