i need the answe to this two step equation the work two please?

Question

3x-1y=5,
x=-2

Answer 1

3x - 1y = 5
x = -2

Keep in mind that the "1" in front of the y is redundant, and we can remove it.

3x - y = 5
x = -2

What we want to do is solve for x and y. But we already have
x = -2, so all we need to do is solve for y. Plug in x = -2 into the first equation to solve for y.

3x - y = 5.

Substitute x = -2, to get

3(-2) - y = 5

Multiply 3 and -2, to get

-6 - y = 5

Move the -6 over to the right hand side to make it +6, to obtain

-y = 5 + 6

Simplify,

-y = 11

Now, multiply both sides by -1, to get rid of the negative sign in front of the y.

y = -11

So your answer is

x = -2
y = -11

Answer 2

Substitute -2 for x in the first equation:

3 * (-2) -1y = 5

-6 -y = 5

-y = 5 + 6

y = -11

Answer 3

3x-1y=5, you dont need the one in front of y because it is implied that there is a one there if no other number is provided. (the work 'too', go back and learn grammar as well)
x=-2

3(-2) - 1y =5
substitute -2 for x
-6-y=5
+6 +6
add 6 to both sides
-y=11
/-1 /-1
divide 11 by -1

answer is y= -11

/ -this symbol means divide by

do your own homeowrk for petes sake, damn

Answer 4

3(-2) - y = 5

-6 - y = 5

-y = 5 + 6 by adding 6 to both sides

-y = 11 now divide by -1

y = -11

Answer 5

3x-1y=5,
x=-2 substitute

3(-2)-y=5
-6-y=5 add 6 to each side
-y=11 divide by -1
y=-11

(-2, -11)

Answer 6

3(-2)-1y=5
-6 - y = 5
-y = 5 + 6
y = -5 -6
y = -11
Solution: {(-2; -11)}

Answer 7

sub -2 for x

3(-2)-1y=5
-6-1y=5
-1y=11
y= -11

Answer 8

3*-2 - y = 5
-6 -y = 5
y = -6 -5
y = -11
