Thanks I get it now. I just couldn't figure out why they got 1000/3 and I got 8/0.024. I don't know why I didn't see that, just simple algebra.

First set up problems to solve each one assiging variables to each unknown. Remember, you need the same number of problems as you have variables.

16 years ago

to solve with substitution is simple. Set the second problem equal to y. then insert this value in for y in the first equation. 6x+9y=(-12) y=27+5x 6x+9(27+5x)=(-12) Take is from here.

16 years ago

to solve for y in terms of y just set the equation equal to y. Then divide everything by the coefficiant of y. #1) 2x+7=y (already correct) #2) x-(2/3)y=3 x-3=(2/3)y (move y by itself) (x-3)/(2/3)=y (divide by 2/3) -->(3x-9)/2=y (simplify)
