i think the answer is -12/3 = -4
if this is (-2) - 10/3 , then the first thing you want to do is get everything with the same denominator
so -2 *3/3 = 6/3

so the problem is really -6/3 - 10/3
or -16/3
does that make sense?
yes thats what i got then you have to divide by 4. so then multiply by the reciprocal and i got -16/12 which simplifies to -4/3 right?
hmmm, what do you mean divide by 4?
well that was part of the equation. its x + 4z=-2 and x= 10/3
oh I did not see that part. so you're solving for z
yeah i didnt include it in my question but yeah solving for z
so right 4z = -16/3
so to isolate z, you divide both sides by 4
so z = -16/(3*4) = -16/12 = -4/3
also, go ahead and plug it back in to the equation
thats exactly what i had but the book said 1/3
since now you have both the x value, and the z value
put them back in and make sure the equation holds true
(even if you just use your calculator)
the book said -1/3
yeah ill try it
if you put them back in, then 10/3 + 4*(-4/3) = - 2
so 10/3 - 16/3 = -2
-6/3 = -2
-2 = -2
so you were right, back of the book was wrong :p
lol okay good cause that was really irritating me i was sitting there thinking "how am i wrong?!" ahah
haha yeah =) it's good you questioned it :)
thank you
