Webb31 maj 2014 · What’s the Problem? “Equations are easy sir”, says the Year 9 student, “you just grab a number, chuck it on the other side of the equals, and it changes sign”. So, in the first example the divide by negative 5 becomes a multiply by positive five, and in the second example the plus three gets magically transformed into a minus three. Webb1) by hand First note that if we write a = 5/b based on the first equation and substitute that into the second equation we get sqrt (5/b * b^2) = sqrt (5 * b) = 10 so b = 20 and a = 0.25. 2) solve Regarding the use of solve these equations can be transformed into linear form by taking the log of both sides giving: orange business services bangalore https://peaceatparadise.com
