S1 : Logarithm of a number x is defined for all negative values of x. S2 : Logarithm of 1 to the base x (where x>1) = 0
The solution for the equations c1x + b1y + a1 = 0 and c2x + b2y + a2 = 0 is
S1 : x = (b1a2–b2a1)(c1b2−c2b1)
S2 : y = (c1a2–c2a1)(a1b2−a2b1)
The graph for the following system of equations :
2x+3y=5 and 6x+9y=40 is shown
S1:a1a2=b1b2≠c1c2
S2 : The two lines intersect each other.
