Is -4c>7;c=-2 a solution or inequality

2 answers:

8 0

C = -2 will work as a solution.

We know this because of we substitute -2 into the equation:

-4(-2) > 7

8 > 7

It comes out true, because obviously 8 is greater than 7

Hope this helps :)

X-Y-2Z =-11 X-2Y-Z = -11 -X+Y+3Z = 14

Snowcat [4.5K]

9514 1404 393

Answer:

(X, Y, Z) = (-2, 3, 3)

Step-by-step explanation:

We can subtract the second equation from the first to get ...

Y -Z = 0

We can add the third equation to the first to get ...

Z = 3

Then ...

Y -3 = 0 ⇒ Y = 3

and ...

X -3 -2(3) = -11

X = -2 . . . . . . . . . add 9

The solution is ...

(X, Y, Z) = (-2, 3, 3)
