1. If7 4 3x   and1xy  , what is the value of2 21 1x y

7) 3x+Y=1 and 5x-Y=7 then x = _____Question 4Answera.x=0 y=1b.x = -1 y=2c.x=1 , y = -2d.x= -1 y = 3

Given that y is inversely proportional to x and y=21 when x=6, find the value of x when y=14.

4x - y = 7 y = 3x + 1

Evaluate −1x + 7y + 4x + 1y; for x = 4 and y = −2.

Evaluate the following expressions and get value of x and y by hand.x = 3 + 4 – 7 * 8 / 5 % 10y = 3 / 2 + 3 * 8 / 3 – 3 + 1.5 / 3Write a C program and check your answers
