Question

find four solutions for 4=5x-3y

Answer 1

8. Find four different solutions of the equation 5x + 3y = 16.
four different solutions are
5(0) + 3y = 16
3y=16
y=5.3
(0,5.3)
5x+3(0) = 16
5x = 16
x = 3.2
(3.2,0)
5(1) + 3y = 16
5 + 3y = 16
3y = 16-5
3y=11
y= 36
(1,3.6)
5x + 3(1)=16
5x+3=16
5x=13
x=2.6
(2.6,1)

Answer 2

(1)take x= 5and y=7

then according to question

4=5×5-3×7

4= 25-21

4=4

LHS =RHS

(2)Take x=2 and y=2

then according to question

4=5×2-3×2

4=10-6

4=4

LHS =RHS

(3)TAKE x=8 and y=12

then according to question

4=5×8-3×12

4=40-36

4=4

LHS=RHS

(4)Take x= 13 and y =23

then according to question

4=5×13-3×23

4=65-69

4=4

LHS =RHS
