Question

Solve the equations 3x+2y=5 and 3x-2y=1 by elimination method.​

Answer 1

3x+2y=5.......(1)

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

subtracting equation 1 by 2

3x+2y=5

3x-2y=1.

- +. =-

_________

3x-3y+2y-(-2y)=5-1

2y+2y=4

4y=4

y=4/4=1answer

adding equation 1 &2 we get

3x+2y=5

3x-2y=1

+

________

3x+3x+2y-2y=5+1

6x=6

x=6/6=1

:.x=1&y=1

Answer 2

x = 1

y = 1

Explanation:

3x + 2y = 5

3x - 2y = 1 (subtract these equations)

––––––––––––

4y = 4

divide by two

y = 1

input y = 1 the other equations

3x + 2 = 5

simplify

3x = 3

x = 1
