Question

5(x+3)- 3(y+2)=18 7( x-2)-5(y-3)=12

Answer 1

Answer:

x=3 y=2 is the solution

Answer 2

Step-by-step explanation:

5(x+3)- 3(y+2)=18, 7( x-2)-5(y-3)=12

5x+15-3y-6=18

7x-14-5y+15=12

5x-3y=9 (Eq-1)

7x+5y=11 (EQ-2)

multiply 5 in Eq-1 multiply 3 in Eq-2

then we get,

25x-15y=45 (Eq-3)

21x+15y=33 (Eq-4)

subtracting both equations (eq-3, & eq-4)

We get,

4x= 12

x=3

putting value of x in 5x-3y=9

We get , 5×3-3y=9

15-3y=9

15-9=3y

3y=6

y=2

X = 3 , Y = 2
