Question

i try to solve this in fractions but i had a hard time to know this i tried solving it but my answer's are wrong when i check it help me.......!!!  x-3y=7 and 4x+y=6 in substitution way.

anonymous · Answer

solve for x in the first equation:

x-3y = 7

making

x = 7 + 3y

then, substitute the value of x to the 2nd equation:

4(7+3y) + y = 6.

Now try to solve it.
