What is -9x-(2x/-3) When x equals 7

Answers

Answer 1

Answer: $-9x- (2x)/(-3)$

$-9*(7) - (2*7)/(-3)$

$9*7 = 63$

$(2*7)/(-3) = (14)/(-3)$

Apply the fraction rule : $(a)/(-b) = - (a)/(b)$

$= - (14)/(3)$

$-63-( -(14)/(3) )$

Apply rule - ( - a) = a

$-63+ (14)/(3)$

Convert element to fraction :

$63 = (63)/(1)$

$-(63)/(1) + (14)/(3)$

Find the LCD 1*3 = 3

$- (63*3)/(3)+ (14)/(3)$

$(-3+63+14)/(3) = (-175)/(3)$

Apply the fraction rule : $(a)/(-b) = - (a)/(b)$

$= - (175)/(3)$

hope this helps!
