Answer Choices:
(2, 2)
(2, -2)
(2, 1)
(-2, 2)

Answer 1

-.2x -.3y= .2
.4x - .3y=1.4
get a variable alone. for this im gonna get the x alone
-.2x= .3y+.2
now to try and get one POSITIVE x
-5(-.2x= .3y+.2)
x=-1.5y+1
now we have an x value to work with. sense we solved it using the first equation, were gonna plug it into the second equation.
.4x - .3y=1.4
(-1.5y+1)-.3y=1.4
-1.8y+1=1.4
geth the variable alone
-1 on both sides
-1.8y=.4
divide both sides by -1.8
your answer for y is .2
plug into the first equation
-.2x -.3y= .2
-.2x-.3(.2)=.2
-.2x-.6=.2
add .6 to both sides.
-.2x=.8
divide by -2
x=-.4
so x=-.4, y=.2
