Exercise 12.2 question 14, $y(3 + x) = x(6 + y),\; 3(3 + x) = 5(y - 1)$ , is asked to be solved by which method?

asubstitution
belimination
ccross-multiplication
dgraphical

ব্যাখ্যা

The problem explicitly directs the use of cross-multiplication, the method that solves a linear system in two variables directly from its coefficients. After simplifying both equations to the form $ax+by+c=0$ , the cross-multiplication formula is applied.
