is these equations are solve like this:

Question

2x+y-3=0
x+2y+3=0

is these equations are solve like this:

anonymous · Answer

Multiply first equation by 2

4x + 2y - 6 = 0
x + 2y + 3 = 0

Subtract them:

3x = 9

x = 3

Put the value of x in any of the above equation and find the value of y..

Can you do it or not??

@waterineyes I want to solve it simultaneously:

look
$$x/(1)(-3) + (2)(3) = -y/(-3)(2) + (1)(3) = 1/(2)(2) +(1)(1)$$

Are you referring to the reduction method?

zepp · Answer

If so

(x+2y+3=0)*2 = 2x+4y+6=0
