Question

solve the following simultaneous equations : (1) 2x + 3y = 7 ; 2y - x = 0

Answer 1

Answer:

2x+3y=7......................(1)

2y-x=0

x=2y.............................(2)

substitute the value of x in equation (1)

2x+3y=7

2(2y)+3y=7

4y+3y=7

7y=7

y=7/7

y=1

substitue the value of y in equation (2)

x=2y

x=2 x 1

x=2

solution (x,y)=(2,1)

Answer 2

Answer:

Solve, 2x+ 3y = 7 , 2y-x = 0.
