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:
C
Step-by-step explanation:
this is quite confusing
Answer: 1/2
Step-by-step explanation: we have formula y = mx + b
x - 2y = 4
2y = x - 4
y = x/2 - 4/2
y = x/2 - 2
m = 1/2
