Question

(a) 4x - 3y = 6,

Answer 1

A.4x=3y+6 we found the x that x=+3/4+3/2
Then we substitute x=+3/4+3/2 to the second equation (7x+3y=27)and we do the calculations to find y
7(3/4+3/2)+3y=27
21/4y+21/2+3y=27
21y+42+12y=108
33y=66
Y=2
We substitute y (2) to the first equation 4x-3y=6 to find x
4x -3(2)=6
4x=12
X=3
