Find x and y if 3[4 x] + 2[y -3] = [10 0] - Vidyadip

Question

Find x and y if 3[4 x] + 2[y -3] = [10 0]

✓

Answer

3[4 x] + 2[y -3] = [10 0]

[12 3x] + [2y -6] = [10 0]

[12 + 2y 3x - 6] = [10 0]

Comparing the corrresponding elements we get

12 + 2y = 10 and 3x - 6 = 0

Simplifying we get y = -1 and x = 2
