5x+4y=122 Do we solve for x first and then y? I came out with x=24.40-4y y=35-5x Not sure what to do with this?
1) 54+27=9.6+9.3=9(6+3)=9.9=81 2) 60x-84=12x*5x-12*6 3) 42x+28y=7x*6x+4y*7y I am stumped on (2) &(3) ...
I am stumped: I tried solving for y, lcf 12 for x (-3) 4x-9y= -13 (4)3x=2y=34 -12x+9y=39 12x+8y=136 everything went wonky... 17y=-97 /17=/17 y=1...

3x-2y= -1 3x-4y= 9 by adding, I get: -6y=8 /6=/6 y=4/3 ? Do I need to multiply bottom equation by -1, before adding? 3x-2y=-1 -3x+4y=...
x-y=4 x-2y=10 I came up with y=-4 2/3 Or y= -2 And I don't think either works back in the system:(
-X + X=5 X-5X=-9
2x-y= -6 x+y= -6 started with x+y= -6 x=-6 - y then 2( -6-y) -y = -6 -12-2y-y= -6 -12-3y=-6 -3y= -18 y= -6 x+ -6=-6 x=0 so...
