Type the correct answer in the box. Use numerals instead of words. What is the solution to this equation?
7 - 32
- I = 12
The solution is r =

Step-by-step explanation:

we have to just keep in mind to do the same operation to both sides of the equal sign

; subtract 7 from both sides

; multiply both sides by -1

; raise both sides to the power 3

2-x = (-5)³

2-x = -125 ; subtract 2 from both sides

-x = -125-2

-x =-127; multiply both sides by -1

x= 127

8121 because

130,000 divided by 16 is 8121

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
