Answer:
x= 6/5y+6/5
x= 2/3y+6
Step-by-step explanation:
3x-18=2y
Step 1: Add 18 to both sides.
3x−18+18=2y+18
3x=2y+18
Step 2: Divide both sides by 3.
3x/3= 2y+18/3
x= 2/3y+6
#2
5x−6y=6
Step 1: Add 6y to both sides.
5x−6y+6y=6+6y
5x=6y+6
Step 2: Divide both sides by 5.
5x/5= 6y+6/5
x= 6/5y+6/5
Answer:
x =12 and y =9
Step-by-step explanation:
3x -18 = 2y or 3x -2y = 18
5x-6y = 6
Using elimination method
In order make coefficient of y in both equation same with different sign ,
we multiply equation 1 by -3 and adding the obtained to equation 2
-3(3x-2y) = 18x-3
-9x +6y = -54
5x -6y = 6
-----------------------
-4x = -48
x = [tex]\frac{-48}{-4} = 12[/tex]
on plugging the value of y in equation (1) ,we get
3(12) -18 = 2y
36 -18 = 2y
2y = 18
y = 18/2 = 9
x = 12 and y = 9
