simultaneous equations HELP!!

Rearrange one equation to make it x= or y= and then just sub it into the other equation. One of the unknowns won't be there, when you have the answer for one sub it back into a equation for the other unknown.

If you post an example question, or one you're specifically stuck on, we'd be able to put the method into context so you'd understand easier

But yes, as chloe_32 stated, I would rearrange either equation 1 or 2 and substitute it into the other.

For example;

If we have

Equation 1: $3x+5y-24=0$ and
Equation 2: $5x+8y+36=0$

If we take Equation 1 and rearrange for $x$ we get:

$3x=24-5y$

$\Rightarrow$ $x = \dfrac{24-5y}{3}$

Now if we substitute this into Equation 2

$\dfrac{5(24-5y)}{3}+8y+36=0$

Now we can solve Equation 2 for $y$

You would get $\dfrac{120-25y}{3}+8y+36=0$

$120-25y+24y+108 =0$

$\Rightarrow$ $y=228$

Now, let's substitute this $y$ value into equation 1 to get the $x$ value.

$y=228$

$3x+5y-24=0$

$3x + 5(228)-24=0$

$\Rightarrow$ $x= -372$

Therefore you have $x= -372$ and $y=228$

Hope this helps


P.S. I made the question up on the spot, don't be thrown off by the answers, concentrate on the method instead

Thank you so much!! In regards to the specific example how would you work out:

4x + 6y = 12
x + y = 1

Thank you so much!! In regards to the specific example how would you work out:

4x + 6y = 12
x + y = 1
