2 X + y =8 and 3 x - 2 y = 5 method of cross multiplication​

Answer»

Answer:

\text{GIVEN EQUATIONS are}

2x+y-5=0

3x+2y-8=0

\textbf{By CROSS multiplication rule,}

\displaystyle\frac{X}{-8+10}=\frac{y}{-15+16}=\frac{1}{4-3}

\displaystyle\implies\frac{x}{2}=\frac{y}{1}=\frac{1}{1}

\implies\;x=2\;\text{and}\;y=1
