Answer:
[tex]x=2\frac{1}{2}[/tex]
[tex]y=3\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]2x - 3y = -10; ~10x - 6y = -5[/tex]
[tex]2x - 3y = -10 * 2[/tex]
[tex]10x - 6y = 5[/tex]
[tex](i)4x - 6y = -20[/tex]
[tex](ii)10x - 6y = 5[/tex]
[tex]eqn(ii) - eqn(i)[/tex]
[tex]6x = 15[/tex]
[tex]x=\frac{15}{6}[/tex]
[tex]=\frac{5}{2}[/tex]
[tex]x=2\frac{1}{2}[/tex]
