Solve analytically using the substitution method 6x3y4 x2y4S

Solve analytically using the substitution method. 6x-3y=4 x+2y=4

6x-3y=4 ----(1)

x+2y=4 ----(2)

From equation 2: x= 4-2y

Substitute in equation 1:

6(4-2y) -3y =4

Solve for y:

24 -12y -3y =4

-15y = -20

y = 4/3

x = 4 -2y = 4 -8/3 = -4/3

Solution : (x , y) = ( -4/3 , 4/3)
