Question

Solve each simultaneous equation
X+Y=264
X-Y=208

Answer 1

add both of them to get x, then substitute in any of the eqns to get y....

Answer 2

So add the two numbers together

Answer 3

nope
add the two equations both the sides, y gets cancelled then simplify to get x

Answer 4

Can you show me??

Answer 5

ahhhhhh...

x+y=264
x-y=208

2x=264+208

2x=272

x=136

put it in y

y=264-x

y=264-136

y=128

hope its correct

Answer 6

Thanks

Answer 7

2x=264+208
2x=472
x=236
when u substitute in y=264-x
y=264-236
=38
