Answer:
Step-by-step explanation:
[tex]\frac{2x}{a}+\frac{y}{b}=2 ---------(i)\\\\\frac{x}{a}-\frac{y}{b}=4-------------(ii)\\\\[/tex]
Add the equations. So, y/b will be eliminated.
[tex]\frac{3x}{a}=6\\\\x=6*\frac{a}{3}\\\\x=2a\\\\[/tex]
x= 2a
Substitute x = 2a in equation((i)
[tex]\frac{2*2a}{a}+\frac{y}{b}=2\\\\4+\frac{y}{b}=2\\\\\frac{y}{b}=2-4\\\\\frac{y}{b}=-2\\\\y=-2b[/tex]
y = - 2b
