Solve for x and y respectively 3x - 5y = 9 6x - 4y = 12

Solve for x and y respectively
3x - 5y = 9
6x - 4y = 12

Answer Details

3x - 5y = 9 ------x2
6x - 4y = 12 -----x1
6x - 10y = 18
-6x - 4y = 12
____________
$\frac{6y}{-6}$ = $\frac{6}{6}$
y = -1
in eq (1) 3x - 5y = 9
3x - 5(-1) = 9
3x + 5 = 9
3x = 4
x = $\frac{4}{3}$
