What is 11twefths of 24
i understand how you got the answer i just don't get why i don't put 5x+4y before the equation because i have been for all the other ones and i got those ones right.. for example this one: 6x+5y= 7 x-y= 3 i isolated the second equation into y=3+x so: 6x+5y(3+x)=7 6x+15...
x+2y=3 5x+4y=8 I isolated x+2y=3 to make: x=3-2y then i began to sub in equation one with equation two: 5x+4y(3-2y)=8 5x+12-8y=8 after that i began to try to solve the equation but my answers were not correct. any help would be greatly appreciated!
