How do you solve the system of equations #2.5x+y=-2# and #3x+2y=0#?
x = -2, y = 3
Rearrange one of the equations to give an expression for one of the variables in terms of the other i.e.
It doesn't matter which eqn we start with, so rearranging eqn1
Put this value for
multiply out and simplify
Now put this value for
We can start with either eqn and find either
