Solve the simultaneous equations
3x - 4y = 18
9x + 2y = 12

3x - 4y = 18

9x + 2y = 12

Solve for x in the first equation.

3x - 4y = 18

3x = 18 + 4y

x = (18 + 4y)/3

x= 6+4/3y

Put x as 6+4/3y in the second equation and solve for y.

9x + 2y = 12

9(6+4/3y)+2y =12

12y+54+2y=12

14y+54=12

14y=12-54

14y=-42

Put y as -3 in the first equation to solve for x.

3x - 4y = 18

3x - 4(-3) = 18

3x+12=18

3x=18-12

3x=6
