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:
there is no solution
Step-by-step explanation:
y = 2x + 1
put into other equation
2x - 2x + 1 = 3
0x + 1 = 3
0x = 2
0/0x = 2/0
x = undefined
Answer: -0.22222222...
Step-by-step explanation:
-2 over 9 can be written as -2/9
So that’s basically -2 divided by 9. If you’d do long division properly, you should get -0.22222222...
