Ok. I'll explain it as well.

- anonymous

please i really wanna understand , not just get the answer ^^ (:

- pooja195

Plug in equation 1 into equation 2
3x + (x+3) = 19
now solve for x

- pooja195

Combine like terms :)

- anonymous

oh okay so it would be 4x+3=19

- abb0t

You can rearrange, using algebra tricks, to manipulate an substitute.
That means you can rearrange equation 1: \(\sf \color{red}{y-3 = x}\)
notice it says x equals y - 3?
well, yeah, thats what it equals to, so substitute THAT thing that x equals to into equation 2: \(\sf \color{blue}{3}(\color{red}{y-3})\color{blue}{+y=19}\)

- pooja195

right subract 3 from both sides
4x=19-3

- jjamz87

y = x + 3
3x + y =19
plug in the first equation into y
3x + (x + 3) = 19
simplify
3x + x + 3 = 19
4x = 16
divide 4 from both sides.
x = 4

- anonymous

4x=16

- pooja195

whats 16/4 ?

- abb0t

4

- anonymous

4

- pooja195

good therfore x=4
now plug that into the 1st equation y=4+3
whats 4+3?

- anonymous

okay so i just have to rearrange @abb0t for these questions
and plug it in to the other equation

- anonymous

thank you @jjamz87

- pooja195

@awlas15 rearraging makes it more complicated you can leave it as is...

- pooja195

*rearranging

- anonymous

ohh okay so then the answer 4,7

- pooja195

yep

- abb0t

No. Do not listen to her, rearranging is much easier.

- abb0t

It is simply plug and chug and combining like terms.

- jjamz87

@awlas15 yes you are correct

- abb0t

Nice one @jjamz87

- pooja195

@abb0t quit trying to make things more harder than they need to be.
