Answer:
d
Step-by-step explanation:
15x-y=22---(1)
3x+8y---(2)
(1)-(2)x3: -41y=-53
i.e. y=1.2927 (correct to 5 significant figures)
Put y=1.2927 into (1),
3x+8(1.2927)=15
x=1.5528
Therefore, the answer is (1.55, 1.29) (rounded to the nearest hundredth)
*You can substitute the answer back to the equations
e.g. option a is (0.45, 2.47) so you can put x=0.45 and y=2.47 into 15x-y and you will find that the answer is not 22
