X + y = 2
2x - y = 7
Which of the following ordered pairs (x, y) satisfies the system of equations above?
A. (-1,3)
B. (5,-3)
C. (3, 1)
D. (3,-1)

Step-by-step explanation:

from equation 1 we get,

now,

we get,

now,

we get,

hence, the value of x = 3 and y = (-1)

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
