Question

What is the Value of X?

Answer 1

Answer:

x = 27

Step-by-step explanation:

4x+7 = 5(x-4)

4x + 7 = 5*x + 5*-4

4x + 7 = 5x - 20

7 + 20 = 5x - 4x

27 = x

Check:

4*27 + 7 = 5*(27-4)

108 + 7 = 5 * 23 = 115

Answer 2

Answer: x = 27

Step-by-step explanation:

These angles are congruent to each other so we well put an equal sign in between the two degrees.

Distribute the 5 by multiplying x and the -4 by 5 to get, 5x - 20

4x + 7 = 5x - 20

add 20 to the 7

subtract 4x from the 5x

27 = 1x
