Question

If 3 x minus 2 y equal to 5 and 3 y - 2 x is equal to 3 then find the values of x + y

Answer 1

8 is the answer
x+y = 8

Answer 2

Answer:

Step-by-step explanation:

3x-2y=5..............eq(1)

3y-2x=3................eq(2)

so

eq(2) becomes

3y-2x=3

3y=3+2x

y=3+2x divided by 3

y=1+2x/3............(A)

put in ....................(1)

3x-2(1+2x/3)

3x-2-4x/3

9x-6-4x multiply by "3"

5x-6=0

5x=6

x=6/5 is required value of x

so we put in ...................(A)

y=1+2(6/5)/3

y=1+12/5/3

y=5+60/5/3

y=65/15 is required the value of y

solution set {x=6/5,y=65/15}
