40/100×120=4/1×12=48. 1/4×200=50. so 1/4 of 200 is greater than 40% of 120.
You don't need 3 equations to get a general solution. To do this use the equations x-3y-z=0 and -x+2y+0z= -3. Start out by letting z = t. Then solving those 2 equations simultaneously, your x's cancel out leaving you with -y-z=-3. But since z=t, then -y=-3+t or y=3-t. Now sub that in for y in the first equation, along with the fact that z=t to get x-3(3-t)-t = 0 and solve for x. x=9-2t. So a general solution for this would be (9-2t, 3-t, t)
Well first off you multiply the parenthesis 1/4(x-12) you get -1=1/4x-3 then you subtract the one so now the y can be by itself the you get Y=1/4x-2
Dude its easy,you have to count to see how many space there is and when you reach the end you put the number
The first one
is (2,4)
5. is infinitely many solutions
because yu have tovhange the terms plces
