Step-by-step explanation:
21cm × 13cm × 11 cm = 3003 cm³
6x^2/2x^2
.......................
You multiply both equations by a factor to get them to have the same X coefficient, the first by 5 and the second by 2, you get 10x-15y=5 and 10x+8y=28. Then you subtract the equations to get 23y=23, y=1, plug y into first equaition, x=2. Answer is (2,1)
