Solve the following systems of linear equations using algebraic method.
1)3y=112x
3x=y11
2)8x6y=14
12x9y=18

1). 3y=112x
2). 3x=y11
Using equation 1: y = (112x)/3
Substituting into equation 2
3x = (112x)/3  11
x = (11 2x)/9  11/3
x + 2x/9 = 11/9  11/3
11x/9 = 11/9  11/3
solve for x
Then plug x into either equation 1 or 2, and solve for y
2) Use a similar procedure, as shown in problem 1 
X+12+x<44
