Answer:
x=2
Step-by-step explanation:
5x-7=5-x
5x=12-x
6x=12
x=2
Answer:
C
Step-by-step explanation:
We can multiply each equation by a constant so they'll equal either 15 or -15 since that is the LCM.
Since the answer choices want us to make the top a negative 15, we'll do that.

To make the y's cancel out, the second equation would have to have the y's coefficient equal 15.
Let's do that.

So the resulting equations are answer choice C.
Its just a matter of subbing
-7x - 4y = 6....subbing in (-2,2)...x = -2 and y = 2
-7(-2) - 4(2) = 6
14 - 8 = 6
6 = 6 (correct)
so ur solution is (-2,2)
Answer:
m = y2 - y1 / 2 - 3
Step-by-step explanation:
I believe it is asking you to plug in the numbers into the equation.
