Question

need help with system:
3+2x-y=0
-3x-7y=10x

Answer 1

Hellooooooooo?

Answer 2

Solve for y in both equations, then, because y = h and y = j, h must be equal to j. Solve for x, then substitute x in for one of the original equations, and solve for y.

Answer 3

y=2x+3
-3x-14x-21=10x

Answer 4

27x=-21

Answer 5

...?

Answer 6

solve it out.

Answer 7

i still dont understand

Answer 8

isolate x out of 27x=21
then put that value into the x in y=2x+3

Answer 9

if u dont understand how i got to that point, ask

Answer 10

i see now...i think

Answer 11

when in doubt ask.

Answer 12

is it y=122/27?

Answer 13

42/27+81/27=123/27

Answer 14

3+2x-y=0

Move all terms not containing y to the right-hand side of the equation.
-y=-2x-3

Multiply each term in the equation by -1.
-y*-1=-2x*-1-3*-1

Multiply -y by -1 to get y.
y=-2x*-1-3*-1

Simplify the right-hand side of the equation by multiplying out all the terms.
y=2x+3

Answer 15

-3x-7y=10x

Since -3x does not contain the variable to solve for, move it to the right-hand side of the equation by adding 3x to both sides.
-7y=3x+10x

Simplify the right-hand side of the equation.
-7y=13x

Divide each term in the equation by -7.
-(7y)/(-7)=(13x)/(-7)

Simplify the left-hand side of the equation by canceling the common factors.
y=(13x)/(-7)

Simplify the right-hand side of the equation by simplifying each term.
y=-(13x)/(7)

Answer 16

ok thanks

Answer 17

ela its easier if you move y to the right from the getgo. left and right dont matter

Answer 18

you are right, but for most simple people it's easier to stay with what they know. but for me it works either way.
