What is the solution of the system
3x + 2y =18
Y= -2/3x + 12
2 answers:
3x = 18-2y
x= 6 - 2/3y
then substitute in the second equation
Y= -2/3x + 12
y=-2/3(6-2/3y)+12
y= 72/5
then substitute y= 72/5 in the first equation x= 6 - 2/3y
then x = -18/5
Answer:
3x + 2y =18
Y= -2/3x + 12
3x + 2(-2/3x+12) = 18
3x + (-4/3x+24) = 18
3x + -1 1/3x +24 =18
1 2/3x +24 = 18
1 2/3x = -6
5/3x = -6
x = -3.75
