Question

-X + 2y = -4
7x + 3y = 11
Please help

Answer 1

x=2 y=-1

Explanation:

Multiply 7 for equation -x+2y=-4 to get -7x+14y=-28

Notice -7x can be directly canceled out if you add it to the 7x of the second equation.

-7x+14y=-28

+ 7x+3y =11

------------------------------

17y=-17, you get y=-1

Plug -1 back in the equation of -x+2y=-4

-x+2(-1)=-4

-x-2=-4 add 2 to both side

-x=-2

x=2

Answer 2

x=2, y=-1

as a point it's (2,-1)

Explanation:

system of equation:

-x+2y=-4

7x+3y=11

Let's solve using elimination

multiply the first equation by 7 so we can clear x

-7x+14y=-28

7x+3y=11

add the two equations

17y=-17

divide by 17

y=-1

now subsitute -1 as y into one of the equations.

let's use 7x+3y=11 as an example

7x+3(-1)=11

7x-3=11

7x=14

x=2

If you need it as a point it's (2,-1)

Hope this helps!
