How do you solve #8y-1=x, 3x=2y#?
We can trysubstituting the first equation, for
Using this value back into the first equation:
We have two equations:
We can substitute in the value of x (in terms of y) from the first equation into the second, and then solve for y. Like this:
And then we substitute into either of the initial equations (I'll do both to show we'll get the same answer for x):
