Two equations 1) 5x + y = 21, 2) x - 3y = 9. Eliminate x or y by manipulating equations 1 or 2. Equation 3 = equation 2 x 5 = 5(x-3y) = 5(9) 3) 5x - 15y = 45. Equations 3 & 1 both have 5x's so we can ...

¬(A.B)+A -- given in question. =(¬A+¬B)+A -- using De Morgan's Law. =¬A+¬B+A -- can remove the brackets. =1+¬B -- using identity ¬A+A = 1.=1 -- using identity 1 + anything = 1.
