Convert the proper fraction to a decimal by using long division to divide the dividend(3)(numerator) by the divisor(50)(denominator)
Hence 3/50 in decimal = 0.06
Answer:
(17/8, -1/8)
Step-by-step explanation:
the bottom equation is equivalent to x = 2-y
so I switch the value of x in the top equation to x = 2-y
and it becomes 2*(2-y) - 6y = 5
equal to 4 - 2y - 6y = 5
-8y = 1
y = -1/8
then you substitute this value in the second equation
x + y = 2 becomes x + (-1/8) = 2
x = 2 + 1/8 = 16/8 + 1/8 = 17/8
