simultaneous equation.

Hi, There sre some techniques that can be used for solving quadratic equations. For example: factoring, using the quadratic formula etc. For simulatneous equations there are techniques like substitution and addition method. You could check them out at onlinemathlearning.com/algebra-help.html

practice makes perfect:) do more questions and you'll learn different techniques

Here is a quick lesson in simultaneous equations:- Equ 1 :2x + 3y + 8 = 34 Equ 2 :4x - 2y + 9 = 13 Call each equation a number & make the coefficient of one variable, eg 'x' the same. So Equ 1 multiply by 2 becomes 4x + 6y + 16 = 68 : Equ 3 combine terms ('get rid of x') Eq 3 minus Eq 2 6y -(-2y) + 7 = 55 8y = 48 y = 6 Substitute y = 6 in Equ 1 2x + (3 times 6) + 8 = 34 Arrange terms 2x = 34 - 26 x = 4 You will probably appreciate the space and format of MYLOT Answer Portals are not the best medium for teaching principes - But if you follow the steps I have laid out you should be able to do simple equations - GOOD LUCK :)
