Answer:
x=2, y=-1
as a point it's (2,-1)
Step-by-step 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!
Answer:
x=2 y=-1
Step-by-step 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
