Question

Please I need help this...
what is the solution of 6x + y = 24 and 3x + y/3 =18 ?

a. x=10, y=-36
b. x=24, y= -1
c. x=-12, y=-15
d. x=18, y=1
e. x=-1, y=60

Answer 1

y=24-6x put it in the second equation and get the y and after getting y value then put y value in any equation and get x

Answer 2

A is the correct answer but u should solve u it

Answer 3

6(10) + -36 = 24. Use a calculator and see if that works.
3(10) + -36/3 =18 ? What about this one?

Yes. They both work. The answer is A.

Just try plugging in numbers, if you get the right answer then you've solved the problem.

Answer 4

ah okay thanks for the help you guys

Answer 5

3x+(24-6x) /3 =18
and now taking common 3
3x + 3 (8 -2x) /3 =18
so the 3 and 3 cancel to eachother
3x +8 -2x =18
x=18-8
x=10
now put x into the first equation
6(10) + y =24
60 + y = 24
y=24 -60
y=-36 is the correct answer
i think u have got it how to solve this type of question
