There are different ways to approach solving a simultaneous equation question. For this one I recommend using substitution for this one where you insert one equation into the other.
First take the eq...

x²+10x-3=0(x+5)²-(5)²-3=0 (half the 'x' coefficient and put it in the bracket with x to be squared, then take away that new number squared followed by the original constan...

intergal₀^pi(x^2 + sin^2(x))dx = integral₀^pi(x^2 + 1/2 - cos(2x)/2)dx since sin^2(x) + cos^2(x) = 1cos^2(x) - sin^2(x) = cos(2x)2sin^2(x) = 1 - cos(2x)thereforei...

You must manipulate the fractions so that they both have the same denominator. To do this, multiply the first fraction by 3 and the second by 4 so that they both have the denominator 12. The problem can t...
