How do you work simultaneous equations?

Answer 1

for example:

2x+y=8----(equation1)

and x+y=6----(equation2)

since "y" in both equations r positive and equal we can minus them(equation1-equation2)

2x-x

y-y

8-6

so

x=2

we use this to substitute the x (with 2)

using any equation, x+y=6

i.e (2)+y=6

y=6-2

so y=4

There. That was on way.we should always make either of the variable equal. i.e by multiplying the entire equation.
