Question

What is the value of x? Enter your answer in the box. x =

Answer 1

x = 13

Explanation:

you first must set them equal to each other

( 4x + 7 ) = [5(x-4)]

Then you distribute 5 to (x-4)

you then get (5x-20)

so now in all you have 4x-7 = 5x-20

you then move the 4x by subtracting form both sides

-7 = x-20 is what is left

now add 20 to both sides

your answer is x = 13

Answer 2

x=27

Explanation:

distribute the 5 to the x and -4 then set both equations equal to each other subtract 4x from both sides add 20 to both sides and you're left with x=27
