How do you solve #(18-x)/-9=-5#?

Answer 1

Eva Adamson

#x=-27#

The first step is to multiply both sides of the equation by - 9 to eliminate the fraction.

#cancel(-9)^1xx(18-x)/cancel(-9)^1=(-9xx-5)#

#rArr18-x=45#

subtract 18 from both sides.

#cancel(18)cancel(-18)-x=45-18#

#rArr-x=27#

multiply both sides by - 1.

#-1xx-x=-1xx27#

#rArrx=-27" is the solution"#

To solve (18-x)/-9 = -5, you would first multiply both sides of the equation by -9 to eliminate the denominator. Then, solve for x. The steps are as follows:

(18 - x) / -9 = -5

(-9) * (18 - x) / -9 = (-5) * (-9)

18 - x = 45

Subtract 18 from both sides:

18 - 18 - x = 45 - 18

-x = 27

Multiply both sides by -1 to isolate x:

(-1) * (-x) = (-1) * 27

x = -27

Therefore, the solution to the equation (18-x)/-9 = -5 is x = -27.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
