-2x + 1/2y
= 3/2
x - зу
= 2
Find the value of 'x'.

-2x + 1/2y = 3/2

(x - 3y = 2) ×2

-2x + 1/2y = 3/2

(+) 2x -6y = 4

0 - 11/2y = 11/2

y = -1

substitute y into x - 3y = 2

x = 2 + 3(-1)

x = -1

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
