Could you please teach me how to solve equations of this type?

. . .y = x^2 - 5
. . .3x + 2y = 10

I don't know how to solve it, when they don't have the same exponents
thanks.
 
We really can't teach courses here, so, for lessons, you'll need to look elsewhere.

But, in general, non-linear systems such as this one are solved by substitution. In this case, you might start by plugging "x<sup>2</sup> - 5" in for "y" in the second equation, and then applying the Quadratic Formula to solve for x. Then back-solve for the corresponding y-values.
