URGENT Solve the pair of simultaneous equations using matrix methods.
1) x + y =2 , x + y =3
2) 3x + 2y = 14 , x + 4y =12
3) -3x + 2y = -16 , -x - 5y = -10
4) y = 2x - 5 , 7x - 2y =16

Acompany produces packets of soap powder labeled “giant size 32 ounces.” the actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz and a standard deviation of 0.7 oz. to avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. to avoid losing money, it labels the top 5% (the heaviest 5%) overweight. how heavy does a box have to be for it to be labeled overweight?
