Answer:
x = 10 / 7 (or) 1.43 <rounded to 2 decimal place>
y = - 54 / 7 (or) -7.71 <rounded to 2 decimal place>
Step-by-step explanation:
Another way to rewrite (5x-3y, 3x-y) = (16, 12),
5x - 3y = 16 -- (1)
3x - y = 12 -- (2)
Rewriting (1), y = -5/3x - 16/3 -- (1)'
Substituting (1)' into (2),
3x + 5/3x + 16/3 = 12
14/3x = 20/3
x = 10 / 7 -- (3)
Substituting (3) into (2),
3(10/7) - y = 12
30/7 - y = 12
-y = 54 / 7
y = - 54/7-- (4)
Therefore,
x = 10 / 7 (or) 1.43 <rounded to 2 decimal place>
y = - 54 / 7 (or) -7.71 <rounded to 2 decimal place>
